DOOM 3: Phobos (AppID: 3978420)

In order to launch the mod make sure that Steam version of original DOOM 3 and DOOM 3: Resurrection of Evil is installed

Waking up on Mars with no memory and a wound you can’t explain, you begin a desperate search for answers - about yourself, your past, and the catastrophe looming over two worlds.

You soon meet Samantha Miles, an agent of a sketchy world-wide conglomerate, who claims to know you. As she helps you with your identity, you aid her in the quest to find a long lost friend and missing agent. When the original events of DOOM 3 unfold, the two of you must scramble for safety while still tracking down the missing agent and your identity.

Haunted by fragmented memories and guided by the familiar voice of a girl named Lee, you’ll unearth bittersweet flashbacks, and fight for survival as a mysterious and deadly invasion spreads from the shadows of Mars.

Explore a new set of maps, enemies and story for the beloved old DOOM 3 game.
