The weapon set is slightly different, with the notable change of the shotgun being the first weapon, and there is no pistol with infinite ammo.
The Ultra-Nightmare difficulty level has been removed, with the game now having the same four difficulty level names as Classic Doom, but the other difficulty levels are somewhat tougher than those in Doom (2016). The single player mode is mostly similar to Doom (2016), but there are a few differences.
