This is EXTREMELY difficult, and even though it may seem impossible, it can be done in single player, even though it is easier in Co-Op mode. Throughout Chapter 3 there are 2 types of enemies, male and female. The male are the big fat strong enemies, and the female are the small faster enemies. If you are attempting this on single player, just make sure that the lady hits you before you go on your rampage, an easy tip is to play as Nite Owl for he can block making it easier to know if you have been hit or not. Or if you are doing this in Co-Op simply sit back and let your buddy do all the work.
