What the hell were you thinking
the entire game is totally screwed, you can shoot at the lights to destroy them that causes the guys to look in your direction, but when you shoot a guy that causes them to shoot you. If I were you I would take this piece of crap off and fix it. Because in the tutorial they guys CAN see throught the wall even though it says they can't and they CAN shoot through the wall even though it says they can't as for the first lvl I can't move the map up so I can sneek behind the guys to knock them out.
