I have a game i have been looking for, for years and i suck at describing but here goes.
i believe it came out either early or mid 2000-2007ish
a first person shooter game, you have an african american REALLY buff always wears somekind of sunglasses on police partner, but you basicly almost always only see him in the cutscenes.
You are a police officer or atleast some kind of law enforcement, it is a very violent game, what i can only describe as gritty? graphics. you are able to shoot the weapons out of your enemies hands and they will either cower before your might or try to run away, your antagonist if i remember correctly you meet him and beat him the first time pretty early in the game but he survives and the next times you meet him he wears some kind of fullbody steel armor, looks like it is the only thing holding him together, maps are everything from Urban city combat to sewers and snowy secret mountain bases and on top of skyscapers. also your partner gets killed by mr antagonist right in front of your eyes on his knees in said snowy mountain base if i remember the location correctly.
not sure what more i can write about what i remember I HOPE SOMEONE KNOWS! i have been looking for YEARS!
