As promised, Doom's multiplayer open beta has arrived. It's been available to download the past few days and now you can actually play the thing. Contents include two maps and two play mode (team deathmatch and warpath), while weapons range from plasma rifles, to shotguns, lightning guns and (yes) rocket launchers. The Gauss Cannon also makes an appearance as a power weapon, and you'll even be able to play as a demon, if that's your choice in life. It's live starting today on PS4, Xbox One and Steam.
