Main article: Halloween achievements#2009
|Attack o' Lantern|
Cause the deaths of 5 players by exploding nearby pumpkin bombs.
How to obtain: Keep your eyes on pumpkin bombs near busy areas and shoot at them when an enemy is nearby. Pumpkin bombs respawn rather quickly and deal heavy damage in a large blast radius, so don't hesitate to detonate them.
Collect 20 Halloween pumpkins from dead players to unlock a hat.
How to obtain: There is a 12.5% chance of a Halloween pumpkin being dropped by a player upon death. You can pick up pumpkins regardless of who killed the victim and use the short critical buff to kill more enemies. Obtaining this achievement will reward you with the Mildly Disturbing Halloween Mask.
Kill a Spy disguised as your current class.
How to obtain: Spy-check anyone that is the same class as you with extreme prejudice. This achievement can be earned during any time of the year.
|Ghastly Gibus Grab|
Dominate a player wearing any achievement Gibus hat to earn your own Ghastly Gibus.
How to obtain: Find a player with the Gibus and specifically target him. Unlike the other Scarechievements, this one can be earned during any time of the year. Obtaining this achievement will reward you with the Ghostly Gibus.
Kill a player scared by a ghost.
How to obtain: On Harvest Event or Eyeaduct, players will often stumble into ghosts as they wander through busy areas. On Mann Manor, the Horseless Headless Horsemann will often scare the zealous players who are trying to kill him. Target these helpless enemies before they recover. Ghosts appear on many other Halloween maps, as well. This achievement will work with any wandering ghost.

Kill the Horseless Headless Horsemann.
How to obtain: When the Horseless Headless Horsemann spawns, work with your teammates to defeat him. Consider playing as a fast class, such as the Scout, that can kite the Horseless Headless Horsemann around the map, or a class with high damage output, such as the Soldier. The last three players to damage the Horseless Headless Horsemann when he dies will be credited with this achievement and receive the Horseless Headless Horsemann's Head.
Collect the Horseless Headless Horsemann's Haunted Metal Scrap.
How to obtain: You must damage the Horseless Headless Horsemann with your melee weapon just before he dies. Move in once you see him shiver, which is the beginning of his death animation. Upon the defeat of the Horseless Headless Horsemann, you will receive an Unusual Haunted Metal Scrap.
Collect a Soul Gargoyle in Mann Manor.
How to obtain: A spectral Soul Gargoyle will spawn on the map when there are at least ten players on the server. When one is announced for you to get, search for it while avoiding being killed.
Craft the Saxton Hale Mask.
How to obtain: Acquire the Halloween Masks of all nine classes and craft them together. This Ghostchievement can be earned during any time of the year.

How to obtain: MONOCULUS only stays on the map for 90 seconds, and his appearance will cause both teams to enter a truce, becoming unable to attack or harm one another. MONOCULUS floats in midair, resists rapid-fire weapons such as the Minigun or Flamethrower, and is scarily accurate with its projectile shots. However, it is a large target and attacks against it do not suffer from damage falloff. Mobile classes that can easily hit airborne targets, such as the Scout or Soldier, are effective against it. When MONOCULUS teleports, it temporarily leaves behind a portal to the Underworld. Entering the portal and traversing the Underworld will grant you temporarily increased stats and allow you to stun MONOCULUS when attacking it. Use this opportunity to cause as much damage as possible to MONOCULUS, as he only stays around for 90 seconds. The last three players to deal damage to MONOCULUS when it dies will be credited with the achievement. Completing this achievement will reward you with the MONOCULUS! cosmetic item. This achievement will not work on Hellstone, which features two simultaneous Monoculuses at the final cap point.
|Dive Into a Good Book|
Get to Loot Island and claim your reward!
How to obtain: On Eyeaduct, defeating MONOCULUS causes him to explode in a shower of Jarate and leave behind a purple portal for a short time. Even if you didn't help kill it, you can enter the portal to reach Loot Island, an isolated section of the Underworld. Make your way up the stairs, wait for the cage to lower, and jump into the spooky book to earn this achievement. Since anyone can come through the portal, be wary of enemies who may kill you. Completing this achievement will reward you with the Bombinomicon cosmetic item.

|A Lovely Vacation Spot|
Get to Skull Island and claim your reward!
How to obtain: When Merasmus is defeated, he explodes leaving behind a red portal with a large Bombonicon in the center for a short period of time. Even if you didn't partake in killing Merasmus, you can enter the portal to reach Skull Island. Make your way up the stairs and into the room, wait for the cage to lower, and jump into the hat to earn this achievement. Anyone who makes it through the portal can earn the achievement. Be wary of opposing team members who may attack you without good reason. Completing this achievement will reward you with the Skull Island Topper.
|Wizards Never Prosper|
How to obtain: Like MONOCULUS before him, Merasmus only stays on the map for 90 seconds, and his appearance will cause both teams to enter a truce, becoming unable to attack or harm one another. For basic attacks, Merasmus can perform melee strikes with his staff, throw bombs with the Bombonicon, and launch players upward whilst igniting them. He will also occasionally hover above and bombard the Control Point's area or teleport around the map. If he bombards the Control Point, keep fighting; all attacks on Merasmus at this time are Critical hits. If he teleports, two random players will have bombs placed on their heads; having them run into Merasmus in the given time will stun him. Once Merasmus' health reaches 50% and 10%, he will disguise himself as a prop to stall out the timer; players should then spread out and find the prop that bleeds green blood when attacked. Classes that can attack from a distance, such as the Soldier and Sniper, can avoid Merasmus' melee attacks while easily dodging thrown bombs.
