This is a decent concept for a game which fits the theme well enough, kinda like singleplayer counter-strike in a way. The combat is a bit clunky, it seems you have to get very close to enemies to hit them with the gun and you can't see their shots either. Movement feels a bit slow as well even while sprinting, maybe because the world itself looks absolutely huge relative to the characters. But overall the game works, could be interesting if the combat was a bit more engaging.
