Long time ago i played some first-person shooter and now i can't recall the name.
I remember it is sci-fi game.You play as a soldier of non human army , i think you have some blue skin, vest and helmet.Post apocalyptic environment and i think it is not happening on Earth.I am not sure about enemies, i think you fight against robots, but can't say for sure.You are alone most of the time i think.That is all i can remember.Thank you anyway, and sorry for my bad English.

That's pretty vague. Good luck.
