88For example, the freeze-cam shot of a player's killer helps the player remember specific, troublesome opponents. The nemesis feature adds an additional reminder that certain enemies are more significant than others. It creates a small negative reinforcement loop by giving players an opportunity to score extra points with a revenge kill.

In our more realistic titles, like HL2, these boundaries often require fictional and visual explanations. In the heavily stylized Team Fortress world, however, conspicuous artificiality is a core design principle and so we can simplify or altogether ignore these explanations without compromising the player experience. Playtesting showed, for instance, that these low fences leading to an empty expanse successfully conveyed the message that the area beyond the fence is uninteresting and out-of-bounds."
11N/A"#commentary\tf2-Comment003.wav" "[Ariel Diaz] Each of the Team Fortress classes was designed to make a unique contribution to attack and defense, and control points are, fundamentally, methods of focusing players' attention on these core offensive and defensive activities. They're also useful for drawing players to different points of the map."
12N/A"#commentary\tf2-Comment004.wav" "[Jeff Lane] In our original design, once attackers were cleared off a point, they lost any progress they'd made toward capturing the point. Playtests revealed that lone players near an enemy control point had no incentive to try to capture it if any enemies were in the area. Furthermore, once a team was reduced to defending a single control point, the stronger attacking team was often unable to successfully assault the final point for the full capture period, which caused too many games to end in a stalemate. We changed the capture mechanic so that capture progress persists for a while even after the attackers are cleared off the point, and this improvement fixed both of the problems with the original design.

14N/A"#commentary\tf2-Comment005.wav" "[Jim Hughes] To give players interesting navigation decisions, routes through a map should vary in effectiveness based on the player's current class and the state of the map. Water lets us increase the cost of taking a particular route, because swimming is slower than running. Spies often accept that cost in order to infiltrate undetected. Pyros avoid it because their primary weapon is useless underwater. If the enemy has a strong defense, the increased cost of the water route becomes a worthwhile tradeoff for any class trying to hit the defenders from behind."
15N/A"#commentary\tf2-Comment006.wav" "[Iikka Keranen] We build our 3d skyboxes at 1/16th scale to reduce the memory used by the large spaces in them. This means we have to get a little tricky when dealing with trains moving between the skybox and the player space. There are actually two versions of each moving train; A player-scaled one for the actual gameplay space, and a tiny one out in the skybox. The small repair sheds on either side of the middle building disguise the point at which we swap between the two trains."
16N/A"#commentary\tf2-Comment007.wav" "[Andrea Wicklund] Ideally, matches should end in a victory for one team and a loss for the other. Stalemates are essentially a loss for both teams. To avoid stalemates, our map design considers two key variables: team respawn times and travel time from the respawn point to the frontline. The team that's winning gets slightly faster respawn times and more forward respawn points, a positive reinforcement loop that increases the chances for them to push forward and win the game."
17N/A"#commentary\tf2-Comment008.wav" "[Dave Riller] To accommodate snipers, maps need wide open spaces, long sightlines, and protective cover. Targets of the Sniper require alternate routes that bypass the Sniper's sightlines, though these usually have an additional cost, such as increased travel time. This leaves players with a choice: do they take the more direct, but hazardous route, or the safer yet slower route? Sniper positions generally also have a corresponding enemy sniper deck, positioned on the other side of the arena, which allows one sniper to counter another, offering cover for teammates in exposed areas."
18N/A"#commentary\tf2-Comment009.wav" "[Bay Raitt] Stalemates generally occur around doors, where teams have a strong defensive presence on either side of the opening. To help counter this, we provide alternate routes with high travel costs that become more attractive only when the enemy has strong defenses behind the main route. The number of enemy entry points into an area is crucial to its design, since it's extremely hard to hold an area when enemies approach from multiple fronts. This makes one way exits a useful design tool, since they let us uncouple the number of enemy entry points from the number of friendly offensive routes."
19N/A"#commentary\tf2-Comment010.wav" "[Jamaal Bradley] For gameplay purposes, we sometimes need to neutralize the speeds of the classes. For instance, these central door timers were created to ensure that all classes could make it to the middle part of the map by the time the action actually starts. Playtesting showed that it was more fun to have the teams waiting as a group as soon as the doors open. The anticipation of battle, combined with the hazardous moving trains, creates a great opening clash for the middle control point."
20N/A"#commentary\tf2-Comment011.wav" "[Matt Boone] Bulletproof glass is a useful design tool in strongly defended areas, such as around control points. It gives the offensive team a chance to see enemy defenders and sentrygun positions, while affording the defensive team a good view of the gathering attackers. This is often crucial for the defense if the offense is waiting for a Medic's invulnerability charge."
21N/A"#commentary\tf2-Comment012.wav" "[Matthew Russell] On Attack/Defend maps, stalemates generally involve a weakly positioned attacking team beating its head against the wall as the timer bleeds out. To avoid this, we encourage likely losses to snowball into actual losses as quickly as possible. We start with a short time limit, and then add time whenever the offensive team succeeds in capturing a point. This way the round plays out in as short a time as possible and keeps the tension high throughout. Long round times aren't conducive to the sense of urgency we want to create."
22N/A"#commentary\tf2-Comment013.wav" "[John Cook] Height is a useful feature when designing defensible buildings. For instance, the Cap B building needs to be defended from all directions. The height, and windows on all sides, give defenders in this building an advantage, when launching rockets & grenades from within. Bulletproof glass in some windows lets them safely view approaching enemies."
23N/A"#commentary\tf2-Comment014.wav" "[Jake Nicholson ] For Soldiers, we design spaces with specific attention to height. Soldiers generally want to be shooting down at opponents to maximize the effect of their rockets' splash damage. The rooftop here gives them that advantage. It can also only be reached with the soldier's rocket jump, making it generally inaccessible to the other classes. Because of the splash damage from a rocket jump, soldiers have to trade health for the height advantage. This tradeoff, coupled with the lack of health on the roof, lets usmake the rooftop a powerful advantage without unbalancing the map, since soldiers will need to rely on medics down below to keep them healthy."
24N/A"#commentary\tf2-Comment015.wav" "[Dave Riller] To accommodate the scout class, maps need open spaces that allow scouts to double jump along paths that the other classes can't navigate. This area features a variety of rooftops and rocks that a scout can traverse while staying above any non-scout opponents. Scouts often use their speed advantage to retreat and collect health, so here we force them to adopt some risk by placing the health inside a small, enclosed area, where they sacrifice some freedom of movement."
25N/A"#commentary\tf2-Comment016.wav" "[Matt Boone] The Spy is designed for players who want to outsmart their opponents. At a high level, his gameplay flow is to infiltrate the enemy team, move around while disguised, and use his instant-kill backstab to take out key enemies, usually snipers, engineers, and medics. His invisibility cloak is designed to help him in two key situations. The first is in getting past the frontline, where players are most vigilant against enemies and most suspicious of friends not heading in the right direction. The second is in escaping from enemies who have seen through his disguise while he's in enemy territory. His sapper was designed to allow him to easily take out unattended enemy sentryguns, forcing enemy engineers to keep a close eye on their buildings."
26N/A"#commentary\tf2-Comment017.wav" "[Eric Kirchmer] Balancing the strength of the Engineer's AI-controlled sentrygun was one of more difficult design problems in Team Fortress 2. If the gun was too powerful, only the most skilled players would be able to counteract it. If the gun was too weak, the Engineer would have no chance against skilled players, effectively eliminating any reason to build it in the first place. Our solution was to make the sentrygun essentially binary in the sense that it's lethal to opponents who don't take cover, but can't intelligently deal with enemies popping in and out of cover. This forces the Engineer to use his own secondary weapons skill to compensate for the sentrygun's corner weakness, while still making the sentrygun a formidable obstacle for any opponent simply attempting to sprint past it."
27N/A"#commentary\tf2-Comment018.wav" "[Andrew Burke] The Scout is designed for players who are able to rapidly move around while tracking their target. Where other combat classes rely on high amounts of damage, the Scout relies on his high movement speed and double jump ability to dodge enemy fire. Much of his combat style is crafted through the features of his primary weapon, the scattergun. It does a large amount of damage, but has a wide spread that forces him to get close to the enemy for full effect, where he's also at highest risk of being hurt. It has a slow rate of fire that encourages him to pause to fire, then dodge, then pause, and so on, which gives enemies a higher chance to hit him at intervals. Finally, it holds a small clip and a slow reload time to encourage the Scout to pull out of combat to reload, something which he can do easily with his speed, and gives injured enemies a chance to run before the Scout returns."
28N/A"#commentary\tf2-Comment019.wav" "[Dhabih Eng] The Soldier is a core combat class featuring versatile movement and terrific long range damage capability. He's designed to be comfortable in almost any combat situation, and to be the best long-range anti-sentrygun class. His main weaknesses are designed into his primary weapon, the rocket launcher. It has a small clip size, which forces the Soldier to carefully manage his reloads, and it fires relatively slow-moving projectiles, making it ineffectual beyond short range against any opponent who dodges well, like the Scout."
29N/A"#commentary\tf2-Comment020.wav" "[Charlie Brown] The sniper rifle was another tricky design problem. To meet players' expectations, a sniper rifle has to be able to kill an opponent with a single shot to the head. On the flip side, we need to ensure it can't be snap fired from the hip with the same effect, because then, in the hands of an experienced player, it also becomes the game's most lethal short range weapon, negating the Sniper's primary weakness. To solve this, we implemented a charging damage meter that only appears when the sniper is zoomed. This solution has several beneficial side effects:

The charge time means Snipers can deal out low damage shots quickly or highly damaging shots at slow intervals, which allows opponents to overwhelm them with a coordinated rush. The high damage at the end of the charge rewards Sniper-esque behaviors, such as locating a decent vantage point and taking very deliberate shots.

32N/A"#commentary\tf2-Comment021.wav" "[Marc Scaparro] The Pyro is designed to be the best short-range combat class, aimed at encouraging players to adopt an ambush style of play. To achieve this, we made the Pyro vulnerable in the open, which forces players to seek out enclosed areas and doorways. To add to the Pyro's short range lethality, we made the flamethrower effects visually noisy, which helps disorient opponents long enough for the flames to finish them off."
33N/A"#commentary\tf2-Comment022.wav" "[Wade Schin] The Demoman is the most versatile combat class, capable of rapidly switching from strong offensive pushes to defensive area denial. He has the only indirect fire capability in the game, allowing him to take out sentryguns around the corner, and his sticky bombs give him a grenade jumping ability similar to that of the Soldier's rocket jumps. His sticky bombs can also prevent enemies from moving through doorways, cover a retreat, and defend control points even when the Demoman is somewhere else."
34N/A"#commentary\tf2-Comment023.wav" "[Keith Huggins] With its wide field of fire, the Heavy's minigun lets players who don't have great twitch-aiming skills still wade into the thick of combat. To make up for this reduction in the value of the player's aiming skill, we amplified the importance of other skills. For instance, the wind-up time before firing and the heavy's reduced speed while firing force players to learn to anticipate both the start of combat and incoming enemy attacks."
35N/A"#commentary\tf2-Comment024.wav" "[John Morello] The Medic is the main support class. Previous support classes we've designed had a variety of problems. They didn't require much skill, because they stayed back in defended areas, which also kept them out of the funnest parts of the game. Worst of all, this meant they weren't even terribly useful because they generally weren't near the players who most needed to be healed. We designed the Team Fortress 2 Medic to solve these problems, primarily by focusing on keeping them right in the thick of battle. Additionally, we designed the medigun to be as easy to use as possible, so that Medics can focus on survival while healing teammates. Virtually no aiming is required, which lets Medics concentrate on following their heal target, who has a huge incentive to keep his Medic benefactor safe."
36N/A"#commentary\tf2-Comment025.wav" "[Aaron Halifax] Our main goal in designing the Medigun was to build a strong relationship between the Medic and his healing target. We wanted to see what we would get if we focused on creating a tight loop between two players, instead of just thinking about getting the larger team to cooperate. The Medigun's design ensures that the Medic and his target are extremely conscious of each other, watching their health and relative positions, and making tactical choices carefully. We wanted there to be skill involved in being a good healing target, so that Medics would seek out and latch onto skilled targets. This helps foster the relationship we were after."
37N/A"#commentary\tf2-Comment026.wav" "[Jakob Jungels] Invulnerability adds an element of pacing to the multiplayer experience, which otherwise tends to have fewer emotional highs and lows than a well-crafted single player game. When an invulnerable Medic & his friend come running in, it's an extreme high point for them. It's also a rush for the defenders, who know they've just got to hold on for 10 seconds until invulnerability fades. Invulnerability also sharpens pacing by helping a team push through a defensive stalemate, when the enemy team turtles up and refuses to come out of their base. Without a lack of defensive skirmishers, it's easier for the offense to build up the invulnerability charge without interruption. In addition, invulnerability is a great goal for the Medic and rewards him for being an effective healer. We encourage the behavior by adding more charge when the Medic is healing injured teammates than when he's healing ones who are already at full health."
38N/A"#commentary\tf2-Comment027.wav" "[Jeff Lane] Multiplayer communities tend to focus on a small group of maps, playing them over and over again. Instead of producing a large number of maps, most of which would go un-played, we decided to try and build a single map with more innate replayability than any we'd built before. With most multiplayer maps, you know what you'll be doing before the map has even finished loading. In our case, we wanted a map where you couldn't predict even something as basic as your starting point, let alone what you would be doing when you got there. Hydro therefore begins with a randomized starting state. The emphasis on control of constantly shifting territories means the map rarely feels repetitive. Meanwhile, the explicit round structure keeps teams focused, and provides regular highs and lows as the teams gain and lose territory."
39N/A"#commentary\tf2-Comment028.wav" "[Kerry Davis] Games usually approach stats by comparing the player to everyone else in the world. This is only really of interest to those who are near the top. With TF2 we decided that a better approach might be to compare stats to the player's previous successes, turning them from a worldwide comparative system into a personalized motivational one. The beginning player gets encouragement and acknowledgement that while they're not highly skilled yet, they're getting better all the time. The veterans get to see when they've managed to come close to their previous record, which encourages them beat that record. The personal stat system also acts as a validation system. When a player feels like they've had a really good run, the stats system pops up and essentially says, 'You're right, that was a great run.'"
40N/A"#commentary\tf2-Comment029.wav" "[Andrea Wicklund] The more your art direction can use well-understood visual representations, the less work you have to do to explain your game elements. The earliest version of TF2 had a heavily realistic art direction. As time went on, we found this was causing us a lot of issues. The differences between our player classes were hard to expose satisfactorily. Weapons firing anything other than bullets were hard to visualize. Our maps didn't make a lot of sense in the real world, where two opposing forces rarely build bases within fifty feet of one another. In addition, the game wasn't visually distinct from our other products. A stylized world had none of these problems: Put the massive Heavy next to the pinstripe-suited Spy, and players understand both the numerical health differences between the classes and their very different gameplay styles. The medic's healing beam was easily understood by playtesters when they saw the floating red plus symbols streaming into the target. A stylized fiction can easily explain why the team's bases are built right next to each other. Finally, a TF2 screenshot is easily recognizable, ensuring that no one will confuse it with another of our games."
41N/A"#commentary\tf2-Comment030.wav" "[Moby Francke] Having decided on a stylized art direction, we experimented with a variety of styles before settling on the example of J.C. Leyendecker, an enormously popular illustrator of the early 1900s. Leyendecker's rendering of clothing and material provided a great example of how to add detail to a character while keeping the clean, sharp silhouette shapes that were key to our class identification. We used normal maps to craft folds of clothing, which provided a fine level of detail when seen up close, without detracting from color values meant to draw the player's eyes to the all-important weaponry."
42N/A"#commentary\tf2-Comment031.wav" "[Ariel Diaz] Characters are the most important piece of art in a multiplayer game, so that is where we spent most of our effort. We developed a read hierarchy for player models, prioritizing the information that players needed to be able to read merely by looking at the model. Our hierarchy was this: first, what team they're on, second, what class they're playing, and third, what weapon they're wielding. Team readability was addressed by adopting an overall color palette for each team, picking warm colors for Red and cool colors for Blu. Class readability was addressed through the character's silhouette. Unique silhouette and animation shapes are more identifiable at far distances, and across a broader range of light levels, than any amount of other visual detail on the model.

The short answer is that it took us this long to make something we were happy with. The long answer requires a look at our development process. At its core is the assumption that we don't really know ahead of time what will be fun. We know what has been fun in the past. But if we've got 3 ideas on the table, we can't say for sure which one will be the most fun. So, we've focused on developing a repeatable process that will find out. It's based on a cycle of constant iteration, where evaluation is done by watching as many people play the game as possible. In developing TF2, we tried out many, many features-a few of which made it to the final product, but most of which were cut. For example, our initial versions of TF2 were focused on trying to build a game around the concept of a commander, a single player who had a real-time-strategy view of the battlefield. He was responsible for building structures and providing a unifying strategy for the team. But there were significant design challenges involved. For instance, how do we design the game such that the commander can have fun, and at same time ensure that the players down on the ground can have fun? How do we ensure that the players & the commander value the output of the other? How do we ensure that the game is still fun if you have a terrible commander, or conversely, if you're a great commander with a terrible team? We spent many months working on these and other issues, and never reached a point where we were satisfied. In addition, our game had become overly complex, due to our attempts to add a strategy layer deep enough to warrant the addition of the commander in the first place.

He has the only indirect fire capability in the game, allowing him to take out sentryguns around the corner, and his sticky bombs give him a grenade jumping ability similar to that of the Soldier's rocket jumps. His sticky bombs can also prevent enemies from moving through doorways, cover a retreat, and defend control points even when the Demoman is somewhere else."

To make up for this reduction in the value of the player's aiming skill, we amplified the importance of other skills. For instance, the wind-up time before firing and the heavy's reduced speed while firing force players to learn to anticipate both the start of combat and incoming enemy attacks."
N/A35"#commentary\tf2-Comment024.mp3" "[John Morello] The Medic is the main support class. Previous support classes we've designed had a variety of problems. They didn't require much skill, because they stayed back in defended areas, which also kept them out of the funnest parts of the game. Worst of all, this meant they weren't even terribly useful because they generally weren't near the players who most needed to be healed. We designed the Team Fortress 2 Medic to solve these problems, primarily by focusing on keeping them right in the thick of battle. Additionally, we designed the medigun to be as easy to use as possible, so that Medics can focus on survival while healing teammates. Virtually no aiming is required, which lets Medics concentrate on following their heal target, who has a huge incentive to keep his Medic benefactor safe."

We wanted to see what we would get if we focused on creating a tight loop between two players, instead of just thinking about getting the larger team to cooperate. The Medigun's design ensures that the Medic and his target are extremely conscious of each other, watching their health and relative positions, and making tactical choices carefully. We wanted there to be skill involved in being a good healing target, so that Medics would seek out and latch onto skilled targets. This helps foster the relationship we were after."
N/A37"#commentary\tf2-Comment026.mp3" "[Jakob Jungels] Invulnerability adds an element of pacing to the multiplayer experience, which otherwise tends to have fewer emotional highs and lows than a well-crafted single player game. When an invulnerable Medic & his friend come running in, it's an extreme high point for them. It's also a rush for the defenders, who know they've just got to hold on for 10 seconds until invulnerability fades. Invulnerability also sharpens pacing by helping a team push through a defensive stalemate, when the enemy team turtles up and refuses to come out of their base. Without a lack of defensive skirmishers, it's easier for the offense to build up the invulnerability charge without interruption. In addition, invulnerability is a great goal for the Medic and rewards him for being an effective healer. We encourage the behavior by adding more charge when the Medic is healing injured teammates than when he's healing ones who are already at full health."
N/A38"#commentary\tf2-Comment027.mp3" "[Jeff Lane] Multiplayer communities tend to focus on a small group of maps, playing them over and over again. Instead of producing a large number of maps, most of which would go un-played, we decided to try and build a single map with more innate replayability than any we'd built before. With most multiplayer maps, you know what you'll be doing before the map has even finished loading. In our case, we wanted a map where you couldn't predict even something as basic as your starting point, let alone what you would be doing when you got there. Hydro therefore begins with a randomized starting state. The emphasis on control of constantly shifting territories means the map rarely feels repetitive. Meanwhile, the explicit round structure keeps teams focused, and provides regular highs and lows as the teams gain and lose territory."
N/A39"#commentary\tf2-Comment028.mp3" "[Kerry Davis] Games usually approach stats by comparing the player to everyone else in the world. This is only really of interest to those who are near the top. With TF2 we decided that a better approach might be to compare stats to the player's previous successes, turning them from a worldwide comparative system into a personalized motivational one. The beginning player gets encouragement and acknowledgement that while they're not highly skilled yet, they're getting better all the time. The veterans get to see when they've managed to come close to their previous record, which encourages them beat that record. The personal stat system also acts as a validation system. When a player feels like they've had a really good run, the stats system pops up and essentially says, 'You're right, that was a great run.'"

The earliest version of TF2 had a heavily realistic art direction. As time went on, we found this was causing us a lot of issues. The differences between our player classes were hard to expose satisfactorily. Weapons firing anything other than bullets were hard to visualize. Our maps didn't make a lot of sense in the real world, where two opposing forces rarely build bases within fifty feet of one another. In addition, the game wasn't visually distinct from our other products. A stylized world had none of these problems: Put the massive Heavy next to the pinstripe-suited Spy, and players understand both the numerical health differences between the classes and their very different gameplay styles. The medic's healing beam was easily understood by playtesters when they saw the floating red plus symbols streaming into the target. A stylized fiction can easily explain why the team's bases are built right next to each other. Finally, a TF2 screenshot is easily recognizable, ensuring that no one will confuse it with another of our games."

Leyendecker, an enormously popular illustrator of the early 1900s. Leyendecker's rendering of clothing and material provided a great example of how to add detail to a character while keeping the clean, sharp silhouette shapes that were key to our class identification.

Our hierarchy was this: first, what team they're on, second, what class they're playing, and third, what weapon they're wielding. Team readability was addressed by adopting an overall color palette for each team, picking warm colors for Red and cool colors for Blu. Class readability was addressed through the character's silhouette. Unique silhouette and animation shapes are more identifiable at far distances, and across a broader range of light levels, than any amount of other visual detail on the model.

4747Most classes could carry a standard hand grenade along with a secondary grenade, tied more closely to the class. Team Fortress 2's focus on unique class roles led us to notice that the standard hand grenade was a more powerful combat decider than some of the primary weapons. This made the classes more similar in combat-not a desired effect. In addition, when we looked at some of Team Fortress Classic's map stalemates, they often resulted from large amounts of grenade spam. Two cases were particularly problematic: That of players throwing grenades repeatedly through doorways, hoping to kill any enemies who might be there, and players on the verge of death throwing all their grenades in rapid succession, hoping to get a kill after they die. Removing standard hand grenades made the game more fun almost immediately, especially for new players who were often confused as to why they died, when a grenade went off at their feet. When we examined the class-specific grenades, we found similar problems. Eliminating them from playtests gave us yet another boost in making the game more fun. Once we'd decided on removal, we analyzed each class to see what capabilities might have been lost as a result of the decision. In some cases we added other capabilities, where we felt a class had lost the ability to make some interesting decisions, related to its special grenade type.

The Response Rule system works by listing speech concepts in a simple text file; the game code then makes characters attempt to speak when the rules or conditions defined in the text file are met in the game. For instance, when a player reloads his weapon, this signals the Response Rule system that now would be an appropriate time to speak a line about reloading. The Response Rule system checks the state of the world, and matches it to a set of rules that determine the best line of dialog to use for that speech concept. If the player's health is low, he may speak a different reloading line than if he is completely healthy. He could play a special line if he has killed more than two enemies in the last 20 seconds, another set of lines if he's underwater, and so on.

To justify this, and play up our stylized Spy-tech fiction, we designed the weapons to look like customized pieces of hardware, personalized and modified by each character to suit his own ends.

In this final area of the map, we wanted a freeform battle to rage for some time before anyone could achieve a decisive victory. To achieve this, we built a wide open area with several entrances, and gave players a variety of attack and defense options at various heights. Rather than depend on elevators and ladders, we relied on ramps, since these allow freedom of movement at all times instead of confining players.

The editor also allows artists to connect modular effect 'building blocks' to create complex visual effects. As for the particle system itself, we have offloaded many of the system calculations to the graphics accelerator, which allows us to increase the number of particles onscreen without reducing the framerate."

While these objects have some grounding in reality, they usually diverge in significant ways. For instance, the soldier's rocket launcher fits the general mold of a shoulder mounted rocket launcher, but somehow manages to hold four rockets in a clip. To justify this, and play up our stylized Spy-tech fiction, we designed the weapons to look like customized pieces of hardware, personalized and modified by each character to suit his own ends. In keeping with the industrial theme of the game, we looked to 60's era product design principles for the primary weapons, then focused on musical instruments for secondary and melee weapons, thinking these would reinforce the connection between the secondary items and each character's personality."
N/A59"#commentary\tf2-Comment045.mp3" "[Jim Hughes] When designing areas for high levels of combat, we try to avoid complexity and chaos. Complex geometry confuses players, making it hard for them to track enemies, and interfering with their movement and aiming during combat. The most chaotic combat tends to occur when the size of the room fails to support the number of players fighting in it. In this final area of the map, we wanted a freeform battle to rage for some time before anyone could achieve a decisive victory. To achieve this, we built a wide open area with several entrances, and gave players a variety of attack and defense options at various heights. Rather than depend on elevators and ladders, we relied on ramps, since these allow freedom of movement at all times instead of confining players. Through playtesting we made many changes to the dimensions of the room, the size of cover elements, and the size of the entrances, thus ensuring the area could accommodate a battle of many players. "

We needed an overall theme that justified structures like rock walls and tunnels, but which also had a neutral color scheme. We chose a desert theme with a palette of reddish-brown rock, cool blue sky and neutral light colors that complement the surrounding area. The colors of the seperate areas vary slightly but still key together.

For her role in Team Fortress 2, we had Ellen try various reads on the same lines letting her ad-lib different personalities. On the 5th try, she came up with the winner. Her disappointed and slightly angry evil overlord clearly lets you know, in the world of Team Fortress a tie does not mean everyone wins, but that everyone loses."
63N/A"#commentary\tf2-Comment048.wav" "[Laura Dubuk] This area presented a difficult problem. Since the arena is primarily an interior, there wasn't much we could do to alter its basic structure, so we concentrated on careful management of the interior shapes to create an iconic space. The building is essentially a box with big rectangular windows, contrasted by round elements (generators) in the center. To create depth and parallax, we added linear elements such as railings and cables. We used contrasting values of dark and light on the floor, with walkways to create an interesting value pattern. All these elements work together to draw the player's eye to the flag--which must always be the focal point of the arena."
