Also included in this update: You being scared! [sound of bat wings] That's right, it's the Second Annual Team Fortress Halloween Special. Will there be ghosts? Quite possibly. Will there be exploding pumpkins? You never know. Will you wet your pants in terror? If you're anything like us, emphatically yes.

The Second Annu-Hell Scream Fortress Hauntdead Halloween Special, then also commonly known as the Scream Fortress Update, launched with the October 27, 2010 Patch. Following the previous year's Haunted Halloween Special, the celebration established the annual Team Fortress 2 Halloween event.
This event included the release of the two new Art Pass Contest-winning maps, new cosmetic items, and new Ghostchievements as well as the reactivation of the 2009 Haunted Halloween Special's Scarechievements. The event also inaugurated Haunted Halloween Gift pickups, which was a means of distributing free Halloween-restricted costumes for 5 years.
Although the Scream Fortress page on the TF2 Official Website stated that the event would only last until November 8, 2010, the Haunted Halloween Gift stopped spawning at Mann Manor, and Halloween-only cosmetics ceased to be wearable at around November 8 at 8am GMT. However, Halloween-restricted items like the Spine-Chilling Skull, Voodoo Juju, and Noise Maker continued to be available at the Mann Co. Store throughout the day.
Horseless Headless Horsemann
The Horseless Headless Horsemann is a non-playable character boss, spawning on Mann Manor, who attacks both RED and BLU teams until he is slain. The Horsemann, who is depicted as the undead apparition of Silas Mann, has a health range from 3000 to 9400, depending on the number of players in the server.
- Scream Fortress reintroduced the "Thriller" dance from Michael Jackson's Thriller as a taunt for all classes, originally introduced in the 2009 Haunted Hallowe'en Special. Taunting during the 2010 event would randomly chose between the standard weapon taunt and the Thriller taunt, even if no standard taunt existed for a weapon (for example, the Jarate). The taunt was turned off again at the conclusion of the event.
