Doom RPG Remake Project – a modification to the original part, created by fans of the series. The project takes the player to the UAC base, which is installed on the Red Planet. The main character is an unnamed Marine who is an employee of the space station. He receives the task of arriving on Mars. He finds himself at the base when demons from another part of the galaxy are already invading inside.

Scientists from the UAC discovered ancient scrolls and spells, thanks to which they opened portals to other parts of space. However, terrifying monsters began to emerge from the gates, killing everyone in their path. The central character will have to fight deadly opponents, upgrade his abilities and obtain new, alien weapons. Most of the scientists are already dead, and the Marine will need to confront opponents alone, relying on his skills.

The peculiarity of this remake is that the graphics have been improved and the gameplay mechanics have been expanded. Textures have higher resolution, visual effects now cover more space and look more believable. The characteristics of some types of weapons have been changed, as have the parameters of opponents. The playthrough emphasizes constant combat and frequent battles with powerful bosses. The extensive arsenal includes both melee and ranged weapons.
