code 10-103 means Disturbance. got that from that link, I have yet to try the game yet.
P.S. I was being stupid because I got to level 3 thru the elevator(Including where u start level 3going down the elevator) then I saw the blacked-out guy,(P.S. I didn't try to shoot and I wasn't scared,)and so I pressed tab while approaching the flare,(this is the stupid part) and so I thought I had bugged the game and missed something, so then I restart, and THAT'S when(even tho I knew the person running on edge of screen would be there)I jumped in my seat and started shooting, and so that's the stupid
