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.

It will be hard to maeke a better D3 mod
Absolutely loved many elements of it, like the mini-bosses, the balance of weapons and enemies and the (surprisingly existent) story with the perfect voice-overs!! I hated the level design which opted for convoluted and maze-like for no good reason at all. You can see my gameplays at @RetroGAmesCouple and @RecklessFPSGuy if you don't believe me :)

It's DOOM 3 to the overdrive!
I liked the quicker paced DOOM 3 gameplay, but these Life is Strange teen drama sections feel really out of place. Would not mind a Hell on Earth scenario with these assets tho.

GREAT GUNPLAY AND ACTION BUT...
The unskippable interactive scenes are frustrating and the story gets boring quickly, especially with main character is more like a teenager not a man that can kill space-demons. Also it's often hard to navigate and make progression in this mod, because there ale a lot of non-obvious intractive objects and monitors that simply get missed in a mess of other non-interactive. Overall the gameplay is good and punchy, there is far more enemies and action comparing to doom3 and ROE wich brings new fun expirience which i found great. Especially with a new shotgun, wich is devastatingly hits harder than in orignal one!)
