TDL, correct.
It's basically a game in which everyone is scattered in a large area (we used a wooded area behind our cabin), and the object is to get to the safe area (in this case the cabin) before you get tagged by a zombie.
The catch is that everyone is given an infirmity of some kind, with the exception of a small handful (usually no more than 3). The infirmities include stuff like missing arms, missing legs, blindness, paralysis...after all, this is the zombie apocalypse.
In round 1 I had one arm missing and was guiding a blind person back to the safe area. In round 2 I did the exact same thing except I had no arms.
Round 3 was the funniest because that's when they started getting really inventive. My ailment was that I was afraid of trees and couldn't come within 10 feet of one unless my hand was held. To complicate matters, they started me in an area surrounded by them - so I couldn't escape without help.
At the start of round 3, someone comes by (an ally); I explain my situation, and he said he didn't believe me because I looked healthy and kept going. Since I like to immerse myself in my role, I was trying to act nervous and fidgety in the process. He basically left me to die since I couldn't escape.
Then one of the zombies came up, and I started freaking out - quite literally; I screamed very loudly. I think that was the highlight of my whole weekend. (Chin pushups came a close second.)
