Doom Shinobi – a mod for the original DUM, including the combat system and the concept of battles. The main character becomes a shinobi, an even more deadly character, and in battle he uses a katana instead of firearms. The gameplay takes place in a first-person view, and the user will need to cut opponents into small pieces, using fast weapons and high maneuverability of the ward.

Each attack on an opponent causes him to lose a lot of blood. Because of this, after each battle the environment will be filled with pieces of bodies, severed limbs and blood. As you progress, the difficulty level increases, new opponents appear with even greater parameters and weapons. As in the original version, the protagonist fights demons emerging from the portals of Hell.

The story campaign includes several chapters. Each stage takes the gamer to an original location with its own design, environment and opponents. The central character completely changed his appearance in this project and received a changed characteristic, which helps him run faster and dodge attacks from opponents. In addition to the usual minions of the powerful monster creator, the user will face huge bosses, each of which has its own abilities, weaknesses and strengths.
