I might finally have gone too far with a GTA 5 mod that imports most of Doom 2

A modder has created *Doom 2 in GTA 5 Hell On Earth (D2IGTA5HOE)*, a mod that imports *DOOM2.wad* into *Grand Theft Auto V*, replacing the game’s mechanics with *Doom 2*’s first-person shooter gameplay. The mod allows players to switch between *GTA 5*’s third-person open world and *Doom 2*’s FPS combat by pressing F9, using *Doom 2*’s arsenal against the game’s existing environment.

The mod’s *Hell On Earth* mode, activated with F10, spawns authentic *Doom 2* enemies like demons and Imps in Los Santos’ streets, blending the two games’ aesthetics. However, F10 is also mapped to flossing and Superman mode in *GTA 5*, causing UI conflicts where flossing animations and powers intermittently appear during gameplay.

Players retain access to *Doom 2*’s weapons, including the super shotgun and plasma cannon, which can be used against vehicles, pedestrians, and police. The mod does not replace *GTA 5*’s map; instead, it overlays *Doom 2*’s mechanics onto Los Santos, creating an unintended but functional hybrid experience.

The modder, Josh, has documented the experience with a GIF showing combat at an airport amid a tornado, highlighting the surreal juxtaposition of *Doom 2*’s horror against *GTA 5*’s urban setting. The mod requires players to provide their own *Doom 2* .wad file to function.
