Doom RPG is a mobile phone game developed by id Software and Fountainhead Entertainment. It combines the Doom first-person shooter franchise with role-playing video game elements. The storyline incorporates many similar events of Doom 3, but involves different characters than those in the third game.
The website for Doom RPG does state that the protagonist in Doom RPG is the same character from Doom, Doom II, and Doom 3.
