Zombie Dice 3: School BusExpansion

From BoardGameGeek:

Zombie Dice 3: School Bus, an expansion for Zombie Dice, adds a 12-sided die to the game that's rich with tasty teenage brains, jam-packed with nutritiousness from all their time at school - but those kids are packing shotguns, too, so you might find yourself chowing down on a brain bullet, chasing runners off the bus, getting run over the bus(!), or finding yourself on the receiving end of multiple shotguns.
