The new DOOM not only includes a permadeath mode, but no one at id Software can beat it.
If you're worried that DOOM will be too easy this time around, you can likely dismiss that fear, at least for the included "Ultra-Nightmare" mode. This mode adds permadeath to the game, meaning that each time you die, you're sent back to the beginning of the entire game. All that's left to show that you existed is your helmet, which marks the spot of your demise.
Executive Producer Marty Stratton and Creative Director Hugo Martin told IGN that no one in the studio has beaten the mode yet. In fact, there's apparently a competition within the office to see who can finish it first, and no one has even gotten close.
Permadeath is the only difference between Nightmare and Ultra-Nightmare mode, so if you want the difficulty without the ultimate challenge, you can do that too.
DOOM is set to release on May 13 for PC, PS4, and Xbox One.
