The Rooftop

Zombies can't climb. But you can.
You wake up one morning with the feeling that something wicked this way comes. You're dead right or, you guess, undead right. Zombies spread everywhere seemingly overnight. The movies got it wrong. Zombies aren't stupid, and some of them are fast. They did get something right though, Zombies can't climb, like at all. You can, and have climbed your apartment building, and was never caught. People don't tend to look up. You can't say the same for zombies though.
