“Barotrauma, the 2D submarine simulator from Daedelic Entertainment, first appeared as a Steam Early Access game way back in 2019. After several years of updates, Barotrauma has emerged from Early Access and become a full Steam game. This one allows up to 16 online players to pilot a submarine together while dealing with monstrous sea creatures and other threats,” says Co-Optimus.
