In the last stage, you'll have to run along an elevated platform while dealing with bouncers and butcher zombies. They like to leap at you, so use that fact to your advantage. Let them get near you, then run to the edge of the platform. If you are lucky, the zombies will leap toward you and you can quickly dodge out of the way. They'll fly over the edge of the platform and drop out of your way, leaving you to deal with other threats.
