Zombie SlingChop

Zombies are running wild across the earth, you are one of the last survivors and have devised an ingenious method for combating the 7 billion zombies roaming the earth.

Every apocalypse has its problems. One of the biggest issue a survivor faces with Zombies is ammunition supply. Got a spare 7 billion bullets?

If only there was a way to turn zombies into ammo.....

You cleverly set up a guillotine above your front door. Zombies invite themselves in. Chop! Splat and thump. They slide neatly into a bin. The head bin is placed conveniently beneath a slingshot that's tied between the front window. As zombies roll up to your door, chop off their heads and use them as ammo against the wandering hoards in the streets.

How long will you last? That's up to you.
