Several things:
1. My apologies for the idiocy of my previous posts. I posted the "Ching chong potato" thing to attempt to mock the stupidity and it wasn't very clear, it won't happen again. (Maybe it WAS bluzone withdrawal XD)
2. That would be cool, but perhaps they are just passing through and are only attacking for like a day and then they continue on to their destination. Though I also sort of agree with Awdax that the zombie aspect is becoming more and more background; but since players cannot RP as zombies (because zombies are nonsentient and dead players cannot return), it was rather inevitable.
