Sci-fi roguelike Dome Keeper successfully combines elements of a survival simulator and a fast-paced side-scrolling action platformer. Events are developing on a distant unfriendly planet with a gloomy environment and deadly fauna. But it is valued for its fossils. The protective dome around the base of miners is continuously attacked by waves of local aggressive creatures. Protagonist must by all means and means to resist the threat and save the peaceful settlers.

What lies beneath the domes we know? Dome Keeper The Lost Keepers, a 2026 action adventure simulation from Bippinbits and Raw Fury, answers that question with a full expansion that doubles the original game's scope. You descend into a vast underground network, where abandoned domes dot the caverns like forgotten sentinels. Your mission is to restore power, reactivate defense systems, and piece together what happened to the keepers who came before. The pressure is constant, as each excavation attracts hostile creatures that emerge from the darkness. You must balance mining for rare materials with returning to your dome to repel attacks.
