The Ninja Epidemic

Taking two quick steps forward you bring the bat down over his head and drive him straight to the ground, having snapped his neck with the pressure. You're not sure if he's dead or not so you start clubbing his head until you feel satisfied.

Then you look up and find that three ninjas are approaching you from the group, one in front, two from the sides. Shit. Three on you simultaniously. How are you going to handle this?
