About the game
You crew a submarine heading into a changing undersea trench. One person steers while others load torpedoes, fix leaks and move power between the engines, lights, weapons and shields. Sea creatures attack the hull and can cause trouble inside. You also leave the vessel to explore caves and ruins on foot, collect treasure and find equipment for the crew.
Two to four players cooperate online, with bots available to fill spare places. You need to call out problems and change jobs when damage spreads or a fight demands more hands. Each descent brings another arrangement of places and encounters. Unlockable submarines and clothing give you reasons to return, while the busy repairs and sudden disasters reward a group willing to learn together and laugh when its plans fall apart.
