Dome Keeper builds its roguelike action around a dangerous cycle: defend a dome from alien attacks, then descend below it to mine for resources and relics. The lull is temporary. Players decide whether to return and prepare for the next assault or push deeper in search of more supplies, making each expedition a trade-off between exploration and readiness.
Mining is hands-on: use a drill and keeper equipment to carve tunnels through a procedurally generated map of resources and caves. Bring what you find back to unlock upgrades and gadgets, improving defenses, drilling, or movement. Above ground, operate the dome’s weapons, repair damage, and face enemies that attack by air or ground. Keeper and dome choices, gadgets, difficulty settings, and run modifiers let players shape their approach without changing the central pressure of the mining-and-defense loop.
Friends can defend together in four-player co-op, or compete to survive longest or deliver the most resources. The contrast between a shared defensive task and head-to-head objectives makes its multiplayer format part of the game’s identity, alongside the recurring choice of when to leave the dome and when to dig.
