Set in a distant future, #KILLALLZOMBIES turns civilian survival into televised sports entertainment. The contestants face a ravenous zombie population in an arena, while the broadcast audience gets a say in how dangerous the spectacle becomes. Its premise frames each fight not simply as a battle against the undead, but as a public endurance test shaped by viewers.
That interaction is the game’s defining twist: spectators watching a Twitch livestream can vote on the number and kinds of zombies released, as well as on obstacles. The arena changes as the horde presses in, and the game also offers zombie bosses, a large weapons inventory, varied ammunition, and more than a hundred perks. Those details suggest a survival challenge built around adapting to escalating threats, with audience participation woven into the action rather than kept on the sidelines.
The listed modes are Survival, Local Co-op, and Defend the Vault, and the store categorizes the game as both single-player and multiplayer, including shared-screen co-op. The central experience remains a contest of survival, but its format can involve players fighting together and viewers influencing the arena.
