All of DOOM’s multiplayer DLC is now free with the latest update 6.66.
First, we’ve retired the DOOM season pass and are making all of the multiplayer DLC content available to all players. That’s three multiplayer DLC packs, which include nine of our best maps, three additional guns, three additional playable demons, new equipment, armor sets and more. That’s on top of the modes and features, like bot support, that players have been enjoying since late last year.
You can also try out the game in the upcoming free weekends.
