Dock your subs. Your subs are dice. Dock them at the Rig's stations for power cells, nodules, new subs, gear cards and salvage.
Settle the Crater. The Habitat Foundry, the Pressure Dome and the Dive Bell land habitat pods on the Crater's zones. Each zone you control gives your crew a bonus.
The Ancients wake. Every pod you land wakes them: an Ancient sub rises at the station tied to that zone. After every round they take a turn, one step at a time, and the TV shows the reason for every move.
Win together by landing 5 + number of players pods. Lose if the Pulse reaches 20, the Ancients land 8 pods, take 8 gear cards, or the deck runs dry.
Bots fill empty seats. Co-op, so anyone can take over a bot in the middle of a game.
