Team Fortress 2: Invasion (2015)

The Invasion Community Update was a major community-created update and event added on October 6, 2015. Announced with a community-created Source Filmmaker video, it added four new maps, one of them a themed version of 2Fort, 16 new cosmetic items, 4 weapon reskins, 9 new Invasion-themed unusual effects, and a new taunt. Also included in the update was the Invasion Community Update Pass, which allowed players to directly support the team behind the update and also granted them access to special crate drops and to the Invasion Community Update Coin, which counted kills during the event.
