Bunker X²

Bunker X² is a story-driven post-apocalyptic game that puts you in charge of a subterranean shelter, managing resources, relationships, and the slow-burn transformation of its survivors. Players dig out rooms, run supply teams to the surface, and spend time building bonds with the unique characters who may be the only people left alive. If you enjoy base-management mechanics blended with narrative hangouts, voice-acted scenes and evolving character arcs, Bunker X² delivers an intimate, character-first experience that rewards careful decisions and exploration. Early access begins Monday 17 August 2026 at 12:00 UTC, with a public release planned for September.
