Sleepy Holl0WND Kill the Horseless Headless Horsemann. Reward: Horseless Headless Horsemann's Head Difficulty: Medium 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 firepower, such as the Soldier. The last three players to damage the Horseless Headless Horsemann when he dies will be credited with this achievement.

Gored! Collect the Horseless Headless Horsemann's Haunted Metal Scrap. Difficulty: Medium-Hard 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. As Soldier use the Disciplinary Action and it's extra range (it's range is longer than the Horseless Headless Horsemann's range) to kill him more easily. Upon the defeat of the Horseless Headless Horsemann, you will receive an Unusual Haunted Metal Scrap.

Masked Mann Collect a Soul Gargoyle in Mann Manor. Difficulty: Medium How to obtain: The Haunted Halloween Gift will spawn on Mann Manor or Eyeaduct when there are at least ten players on the server. When one is announced, check nooks and crannies such as the sniper perches or farmhouses, as gifts rarely spawn in the open. Move quickly and kill any nearby enemies to prevent them from grabbing the package.

2011: Eye-chievements

Optical Defusion Kill MONOCULUS! Reward: MONOCULUS! Difficulty: Medium How to obtain: Unlike the Horseless Headless Horsemann, MONOCULUS disappears only ninety seconds after spawning. It may be necessary that both teams stop fighting each other and concentrate on killing MONOCULUS if members from either side want this achievement. MONOCULUS floats in midair, has an innate resistance to 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. Thus, relatively mobile classes capable of hitting airborne targets with large amounts of firepower from afar, such as the Scout or Soldier, make excellent choices for fighting MONOCULUS. 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 when you reappear on the surface world; damaging MONOCULUS when under the influence of the Underworld buff will stun it. 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! Hat.

Dive Into a Good Book Get to Loot Island and claim your reward! Difficulty: Easy How to obtain: When MONOCULUS is defeated, he explodes in a shower of Jarate and leaves behind a purple portal for a short period of time. Even if you didn't partake in killing it, you can enter the portal to reach Loot Island, an isolated section of the Underworld. Defeat any enemies, make your way up the stairs and into the room, wait for the cage to lower, and jump into the spooky book to earn this achievement. More than one person can earn this, meaning killing enemies are only a precaution, not a necessity. Completing this achievement will reward you with the Bombinomicon miscellaneous item.
