Zombicide: Dark Side is a standalone game and a prequel to Zombicide: Invader. It is fully compatible with Zombicide: Invader and all expansions from the sci-fi Zombicide range.
Zombicide: Dark Side is a cooperative game for 1 to 6 players. Play together against the game as Survivors of a subterranean alien invasion! The terrifying Xenos are played by the game itself, using simple rules and a deck of cards. Find weapons, eliminate Xenos, and upgrade your Survivor’s skills with experience. The more Xenos you kill, the more of them are coming! Play 10 missions on 10 different maps made with the included modular map tiles, or create your own missions.
