Doom's campaign will be a bit longer than most modern first-person shooter campaigns. According to a tweet from the game's official account, the campaign will take the average player around 13 hours to complete.

In addition to the campaign, the game will also include a multiplayer component with several game modes, including deathmatch, domination, freeze tag, and clan arena. There's also a Doom SnapMap tool which allows players to construct custom maps, create new game modes and share them with the online community.
Doom releases worldwide on PS4, Xbox One and PC on the 13th of May.
