I think I'll just hang out with Zen. Or:
Pierogies
Tequila
Cigarettes
I'll probably die. I figure I'll have fun on the way out.
To clarify: is everyone dead, or are most people dead? Are the people remaining zombies that I need to shoot at or hide from? Are there buildings? Will there be snacks?
I really need more information as to the meaning of the "end of civilization as we know it" to come up with a more precise list of my needs.
