The Ninja Epidemic

You swing your bat at the ninja and strike a glancing blow accross his chest. Going with the momentum, you lean in with your shoulder and knock him off balance. He falls on his back to the ground. Before he can get up you bring your bat down on his head, feeling it go soft under the force of the blow.

That's two dead ninjas from a simple baseball bat. You turn around to find another ninja coming at you, with nunchaku twirling. He seems skilled with this weapon and you wonder when an opening in his defense will present itself.
