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.

Doom as as story shooter. Great work!

A story driven shooter in the world of Doom 3. Bit difficult at times (at least for me) but I wanted to know what happens next so I kept on going. Worth your time and better than any commercial DLC.

Cool

Schön das gog nun auch Mods offiziell anbietet. Diese Doom 3 - Mod kannte ich bislang noch gar nicht. Eine der ersten Mods war ja Doom 3 classic mod gewesen, welche versuchte die ersten beiden Doom-Spiele aus den 90ern zu rekonstruieren. Mir gefällt diese Mod sehr gut und ist spannend gemacht.

Doom 3 On Steroids!

I picture id seeing this mod in action, saying, "YEAH, THIS is how we INTENDED Doom 3 to play!" It has all the moves the original could not manage so well at the time on most systems, and like an even better BFG than that version they later released. It does begin kind of slow, and reminds me of Soma. But I like Soma; some even compared the look of Soma to Doom 3, but underwater, and I love Irony! Lol. Finally, for hardcore fps gamers I think this would be a five, once the action starts -- but only normal and higher difficulty settings are provided, so I give it four stars for ME to play as a casual gamer. Also no gamepad support, and I'm just better these days with one. I also started with mouse and keyboard years ago, but gamepads are made for games: keyboards are mostly for word processing now, because my hands get too sore. Lol. Otherwise a great mod, with respect for the original, modern improvement and enhancements; I hope for a gamepad option added, so I can better deal with the harder difficulty. GREAT Job: It plays and looks great on Win 10, i5, 16gb, 4gb nv1050 display. WORTH the download!

Great...Now

Was always a bit lacking back when it was just one chapter, and again when it was two chapters, but man with episode 3 added it's incredible, I can't wait to see how they finish off this mod.

Liked Doom 3? Go for it

Definitely fan-made but a lot of fun if you enjoyed Doom 3. Combat is way more fast-paved than the base game. Atmosphere is phenomenal. Solid 7.5/10
