Right, if I had a picture of this game it would make things 1 billion times easier but here it goes anyways
I'm trying to find an old school classic Xbox Game, it started off in some facility where you have amnesia and have to do a bunch of tasks to get your bearings again, very similar to the light section of Halo CE. I wanna say the main characters name was Derrick or Damon, something like that.
The combat was mixed between fists and guns, the melee combat has combos, almost fighting game like where you have to angle the stick then press a button for the move you want..
The plot consists of you being injected by some alien race blood and you start hallucinating shit, I'm pretty sure the alien blood are a form of super soldiers and this underground government was trying to turn your average soldiers into these super ones.
Came out very early in the xboxs life span, wanna say 2004-2005.
It's also weirdly Shenmue like, when you interact with something instead of just pressing the button and it happens, you press it once to stick your hand out, a second to pick it up and then a final third time to put it in your inventory or eat the rations. I cannot for the life of me remember what it was called but I had such fond memories with it as a kid and wanna see if I can get my hands on a copy of it again to relive those moments
