The Engineer

Hydro is a Territorial Control map, and one of the six initial maps included with the game's release. So far, Hydro is the only official Territorial Control map, possibly due to the complexity and difficulty of designing such a map type.

The goal of Hydro is to take over the entire map by capturing "territories". Each game is randomly selected from the six available layouts in a "point against point" game in which both teams must capture the opposite control point while protecting their own. After a team successfully captures the enemy control point, the next round will start, taking place in a different area of the map (which is also randomly selected). After a team captures all four territories, the attacking team must capture the enemy team's base while the opposing team defends for their life. If the Base point is captured, the attacking team wins the round. When the next round begins, territories are reset and a new random game is selected.

In any round of Territorial Control (except in RED/BLU Base rounds), if a control point is not captured within the eight-minute time clock, the game will go into Sudden Death mode.

Locations

RED Control Point 1: The Radar Dish

The Radar Dish capture point.
  • Control Point: The control point is located in a small circular building under a large radar dish. The building is raised up in the center of a large bowl-shaped concrete formation.
  • Entrances from the dam: The radar dish is connected to the dam area via a pair of ground-level tunnels.
  • Entrances from the power plant: The power plant is connected to the radar dish by a large suspended rock formation. This formation is split into two paths with a hole in the middle, the splitting of the path left and right at the radar dish end, and connecting to the turbine room at the other end.
  • Entrances from the warehouse: There are three paths from the radar dish to the warehouse. The first is the large path on the right-hand side of the map. The other two paths are to the left of the main path, one of which goes off to the left (either down to the ground or onto a catwalk), while the middle one connects directly to the raised rocky ledge of the warehouse area.
  • Under the stairs: All of the stairs in the radar dish area can be shot through, and are a common place for Sentry Guns.

BLU Control Point 1: The Power Plant

The Power Plant capture point.
  • Control Point: The control point is located on a metal bridge in the turbine room.
  • Entrances from the dam: The dam area connects to the power plant via three paths. The two left paths connect to an open area outside of the turbine room, which in turn allows access to either the lower area of the building, or the room with the large pipes. The third path is on the right, and goes from the flooded area through a small tunnel and meets with the lower left path.
  • Entrances from the warehouse: The power plant is connected to the warehouse area by the main road, sewer tunnels, and the ventilation system. The main road leads to an area outside of the power plant that allows access either to the lower or middle levels of the building. The sewers connect the warehouse area to the lower area of the power plant, while the vents connect the roof of the warehouse to the room full of pipes next to the main building.
  • Entrances from the radar dish: The radar dish connects to the power plant via a rock formation. Once inside the building, the exits lead either onto the cat walk, or follow the stairs down to the middle of the room.
  • Service room: There is a small windowed room that is next to the bridge. This room is often used as a hiding place for Engineers as it allows them to see attackers without being shot at.

RED Control Point 2: The Dam

The Dam capture point.
  • Control Point: The dam control point is located on top of a raised concrete block in the middle of a large open area with standing water.
  • Entrances from the warehouse: The warehouse area connects to the dam area via an upper and lower path. Both paths converge in a cavern that then splits into an upper, lower, and sewer path. The upper path connects to the ledge overlooking the bridge. The lower path follows the water along the ground under the ledge. The sewer path exits in front of a truck just next to the bridge.
  • Entrances from the radar dish: The dam area is connected to the radar dish by a pair of small tunnels. One tunnel comes out near the flood area spawn room, while the other comes out behind the flood area point.
  • Entrances from the power plant: The power plant connects to the dam area via three paths. One path leads from the ground level and to the right and eventually connects to the long stairs in the dam area. The second path follows the ground around to the left and can either stay at ground level or connect to the top of the long stairs. The final path branches off the second path and leads down a small tunnel to the water area behind the dam area capture point.
  • Second story windows: The dam area spawn room has a second floor that Snipers often use as a nest.

BLU Control Point 2: The Warehouse

The Warehouse capture point
  • Control Point: The warehouse control point is on a low concrete bridge outside of a large building.
  • Entrances from the radar dish: The warehouse area is connected to the radar dish via three paths. The main path hugs the left side of the map. The second path connects the bridge area ledge to the middle of the radar dish area, while the right path comes out on the ledge on the radar dish side.
  • Entrances from the dam: The dam area connects to the warehouse area by two paths. The upper path connects exits above the flood area capture point, while the lower path comes out in the water behind the dam area capture point.
  • Entrances from the power plant: The warehouse area connects to the power plant via the road, the sewers, and the vents. The road leads to a small area that connects to the middle and lower levels of the power plant. The sewers lead to the lower level of the plant, and the vents connect to the room full of pipes adjacent to the main building.

Bugs

  • The boom barrier at the BLU base's entrance is solid when the Power Plant control point is owned by BLU, but not when it is owned by RED and the BLU base is under attack.
  • After a team captures the other team's final control point, it is possible that the map may restart even when it is supposed to end. For example, in Casual mode, winning a match may restart the map instead of ending the game and going to the endgame screen where players can disconnect or vote for the next map, as is the normal behavior.
  • Sometimes, upon a round ending, the previous round will be played again instead of progressing to the next stage. In this case, certain players may remain where they are when Humiliation ends instead of teleporting back to their team's spawn.
  • Very commonly players on RED team will not be teleported to the next area of the level when a round has finished, and must kill themselves to respawn.

Trivia

The yen signature on hydro
  • Hydro appears in Worms: Reloaded as one of the forts.
  • The RED Base that appears in Expiration Date is a modified version of Hydro.
  • Inside the BLU spawn near the power plant, a yen symbol (¥) can be found. This is a reference to the map's creator, Iikka Keränen. It can also be found on Badlands, and a similar symbol can be found on Canals, a map he designed for Counter-Strike: Global Offensive.
  • Two configurations are significantly less common than the others, namely The Radar Dish ⇄ The Dam and The Warehouse ⇄ The Power Plant. This is because these pairs are owned by the same team at the beginning of each game. Therefore, they can only be rolled during the second round at the earliest, when one team has advanced into the other team's territory.
