If im on the last level (Mission 6) where you're outside the compound. I kill the tower guard, gate guard, and guy manning the machine and get in the compound fine. Then I kill everyone on the upper level and take the German Uniform and the papers. I also put away the gun - But when I go down the stairs the Germans seem to recognize me.. I dont know what i'm doing wrong because it worked the first time. Anyone know what im doing wrong?
