DOOM 3: Phobos
Description
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.

A miracle of modding.
Team Future has wrangled Doom 3 into an incredible adventure shooter that polishes many of Doom 3's rough edges. The combat is a little bit punishing, but it isn't particularly difficult - it's a test of executing fresh strategies on a game you thought had already done everything it had. With an original storyline, which might not be everyone's cup of tea, what this group of modders is nothing short of a miracle. It's a must-play for any fans of the original game that want to see more of this old dog, that knows there's more blood left in Doom 3.
