GURPS War Z
Don't fuck with Ouchums; he brought swords and guns to this knife fight.
Eric “Ouchums” Goodemote is on a quest of vengeance. The demise of his personal idol Denny Hecker in the Zombie Apocalypse was too much for him to bear, and he grieved for many moons for the great shogun of used automobiles. One day, while testing a recipe for roasted zombie chicken (which tastes a lot like chicken), Ouchums decided that he would forge his grief into a mighty weapon, vowing that he would not rest until he had turned every zombie in the world into an even freakier looking headless zombie.
