One perk of modern gaming is the ability to play multiplayer with friends or strangers worldwide. Going into Warhammer 40K Space Marine 2, many might not realize this game has a multiplayer feature because it isnt there from the beginning. Instead, players must unlock the multiplayer feature to be able to play with others. Fortunately, once unlocked, players can choose between two multiplayer modes: a PVE mode called Operations and a PVP mode called Endless War.
