Kill more walkers so you don't run out of them! lol
I like the infected wound idea. Could simply be a die roll when wound is received. On a 1, you wound festers 1d6 rounds before you become a walker.
Interested in multistory buildings but only if it doesn't become cumbersome (rule wise). And adds something interesting besides simply a vertical tile.
Something I thought might also be interesting is rival bands of survivors/scavengers.
