Dark Side is a standalone expansion for Zombicide: Invader, providing a full gameplay experience either on its own or integrated into larger campaigns. Players take control of Green Squad, a team of operatives who survived the Xenos threat on PK-L7’s hostile surface, navigating a 10-mission campaign for survival. The expansion introduces the Driller Xenos, a fast-burrowing enemy capable of striking unpredictably from any direction. New equipment, including a Bot and Sentry gun, enhances tactical options for players. Dark Side can also be combined with other Zombicide: Invader sets to create larger, more complex scenarios in the conflict between humans and alien invaders.
