DOOM’s single player campaign weighs in at an average 13 hours, which is fairly reasonable for a modern FPS game. If you’re like me and like to look around, it could easily take you 15 hours.
.@Unreal389 The difficulty level plays a factor, but folks playing at the office average 13+ hours in the campaign

The campaign’s length is reminiscent to id software’s Wolfenstein: The New Order, which also had a hefty single player campaign, yet without multiplayer. DOOM, on the other hand, will provide multiplayer and it did go through two alpha tests as well.
DOOM will be released on May 13 2016.
