The single-player campaign in DOOM will take roughly 13 hours to complete, id Software has stated on its Twitter account when asked how long the campaign will last for.

id Software added that the difficulty level players play on will influence how long the campaign will take to complete, with “folks playing at the office average 13+ hours in the campaign.” Those playing on a tougher difficulty can expect to be playing the campaign for longer depending on their skill.

It is good news then for fans of single-player games that id Software have put a lot of work into making DOOM’s campaign lengthy and filled with gore and action as the game also comes packed with a multiplayer mode.

You can grab DOOM on PS4, Xbox One and PC on May 13.
