The latest free update includes a new arcade mode. This gives players the option to play every level with all guns available as well as Runes and equipment upgrades fully unlocked. Update 4 also comes with Classic DOOM modules to SnapMap which gives you the chance to play and build new maps using assets based on the original games.
Two new multiplayer modes have also been included to DOOM. Possession is a Prowlers vs. Marine mode that puts a team of marines up against several player-controlled Prowler demons. Bloodrush forces players to manage their Bloodrush meter in order to respawn in free-for-all modes.
