Manhunt Cheats

To use a head as a guard distraction, you have to have a machete and

they get red then let go and he will chop off the guys head and you can
pick it up and use it as a distraction like a brick or bottle (ps. I've
only tried it on ground assault, or I think it called that)

The following codes have no effect until you complete both levels with a five star rank on the hardcore difficulty setting to unlock them.
