In response to a fan query, the person managing the account revealed that it takes those in the office an average of 13+ hours to complete the campaign. They added that the difficulty level does play a factor, which is only natural.
As well as a 13 hour campaign, DOOM features a SnapMap editor and a decent multiplayer offering too. It's shaping up nicely in our opinion; judge for yourself from the trailer below.
