I think it was the late 80s or early 90s (operation wolf was around at the time, but that just means after '87 when I SAW the game).
I think it was a 1 player game. (I seem to remember that my brother and I could NOT play at the same time.)
You start with a pistol and on the screen was a first floor and a second floor above. You have to shoot the guys on both floors before they shot you. I think it also had a bunch of doors that you could go in and come out of. You might go up to the second floor or get a better gun.
I think the guy you were playing as had a blue shirt and black pants.
Thanks!
