Grandma with machine-gun: Apocalypsis

Granny is in a hurry to get home and bake some pies. But there’s one problem – first she needs to bake a few hundred zombies! They’ll be chasing you in cars and motorcycles, they’ll have machine guns, rocket launchers, and support drones.
But you’ve got a pretty good arsenal too – from a revolver and machine guns to a minigun and a bazooka.
Help Granny get home, roast them all!
