Boneloaf has announced that its multiplayer party game will have PSVR support, as well as online multiplayer. How VR will be implemented in the game hasn’t been expanded upon, but it will be part of a free update after the game’s release. The update will also see additional story content added too.
Since the gameplay of Gang Beasts involves these creatures fighting each other in various locations it isn’t hard to stretch to the conclusion that the online multiplayer will be players fighting each other.
