About this game
Sail the SS Atlantica across the ocean while Lovecraftian horrors attack from below and hidden traitors sabotage from within. Players manage the ship's dwindling resources, fight Deep Ones on deck, and desperately try to reach port. But some players are secretly cultists working to sink the ship. Every crisis card forces collective decisions where hidden loyalties are tested. A spiritual successor to Battlestar Galactica, rebuilt with a Lovecraftian skin and streamlined rules that cut playtime without sacrificing paranoia.
