The "Grocery Store Zombies" Test

See if you can pass this horribly hard survival test!

1 Your stuck in a grocery store!
2 You find a key!
3 Zombies are out side so you get back in the store!
4 Where do you aim?
5 You kill off enough to relock the door!
6 As the sun comes out, the zombies shrivel up.
7 Your the last man on earth!
