I would forget every one else and live on the Goodyear blimp with my friends, pimped out with extra deck space and cabins. When we ran low on food, water or gas you could just fly low, clear out the zombies with the minigun and jump down on top of wall-mart. Then use pulleys to get the stuff up, then climb a rope ladder to get back. And if I got bored of flying around playing xbox and drinking with my buds. I'd whip out my Cheytac and do some zombie sniping.
Awesome....
