1.sneak up on unexpecting enemy.2.(Note: for this cheat to wrok you must have a drill.) get near him and slowly insert your drill ('m serious, don't stick to him just ur wpn must go through if you bump him you have to redo it) and when its well in spin it and you'll notice that you'll hang on to enemy and then you'll be pushed back and you won't see him anymore. NOTE: if it deosn't work sory
WARNING: my enemy had a rolling pin at back i inserted it there and he fell (screen turns black and enemy falls)

Hope you Enjoy
REMINDER: be quiet slow and percise
Happy Hunting
