The game follows the same rules as the original Doom, pick up keys to get to the exit alive. The player controls can aim in four directions, jump and crouch to avoid enemy projectiles.
Some weapons have different characteristics from the originals. The Shotgun has a shorter range and it shares ammo with the Chaingun. The Plasma Rifle has slow homing bullets. And the BFG has lower damage and lower energy cost than the original.

The game was made in Game Maker Studio. It was released May 13, 2016 the same date as Doom4.
