South Park: The Stick of Truth - You Bastards! Achievement

Achievement - You Bastards!
Have Kenny Die 10 times in battle over the course of the game.

NOTE that this will void the No Child Left Behind achievement if you end a battle with Kenny dead.

The easiest way to do this is to finish the game (i.e. unlock No Child Left Behind first), then go to Canada with Kenny as your buddy. Use Kenny's Rat ability and don't move the control stick. This will automatically kill Kenny and damage all enemies. Finish the enemies off with your character. Repeat against all of the dire animals in Canada, enter the cave, exit the cave, and repeat until you've done it ten times.
