DOOM (it’s important that you capitalise it, because it’s DOOM) will have a single-player campaign that lasts around 13 hours, according to developer Id Software.Responding to a fan on Twitter, a rep speaking through the official DOOM Twitter account said, “The difficulty level plays a factor, but folks playing at the office average 13+ hours in the campaign.”Of course, DOOM isn’t all about single-player. It will have a full multiplayer suite too, offering up game modes including Domination, Freeze Tag, and Clan Arena.
