The year is 1923. The discovery of orichalcum — a powerful mineral found deep in the ocean — has set off a new industrial revolution. Submarines now swarm the depths searching for productive veins, and competition for the richest deposits has escalated into underwater warfare. Meanwhile, the sailors who have returned are talking about things they encountered down there that cannot be explained by resource competition alone. Abyss Crew is a multiplayer cooperative game set aboard a steampunk submarine: one player pilots, one operates the guns, one manages sonar, one handles engineering. Explore the abyss for precious mineral — and pay close attention to whatever it is that is watching you from the dark.
