Full Metal Coffin

Full Metal Coffin is a 3D co-op submarine simulator for up to four players. You and your crew operate a submarine in flooded caverns deep below the Antarctic, fighting for control by eliminating outposts and defending against waves of enemies. The vessel is specially built to withstand the conditions of this new environment.

Operate the submarine

Work together to keep the submarine running smoothly. You can establish a command structure or fill roles as needed; coordination and communication are rewarded. The 3D submarine interior supports up to four players.

Navigate and fight

Use sonar and hydrophones to listen for enemies, and bounce sonar pings off cavern walls to gain advanced vision. Choose engagements carefully, as planning ahead is important to victory.

You can craft unique torpedo types for different situations, then load them immediately or store them for later use.
