The Thanksgiving Update of 2014 was a temporary holiday update to Apocalypse Rising. It changed some of the game's textures, such as trees to orange, brown and other fall colors, changed the zombies to look like turkeys, and changed the name to "Apocalypse Giving."
Zombies[]
Zombies were changed to look like turkeys, and when agrivated, emmit a gobbling sound. When they successfully damaged a player, they would squak. Turkeys heads where reduced in size vastly, but the hitboxes remained the same, resulting in the ability to kill zombies with headshots from above by shooting what appeared to be thier torso.
Terrain[]
Textures in the game were changed vastly, trees were colored shades of orange and brown, and the grass was changed to a orange-brown coleration, in concordance with fall.
