Not sure if someone has said this with all the undead dlc threads here BUT..... I just thought of an amazing thing rockstar could do with the zombies if they make it to multi. Every time a real player or NPC is killed they spawn into a zombie. Now if you're a real player online of course you respawn into your old self again and continue playing, but your former corpse gets up and starts walking. NPC's would just get up and start walking within a few moments.
What would be cool is, depending on the room your in and how many people are playing, doing hide out's, killing each other, would pretty much control the amount of zombie activity. So if it's a room with like 20 players doing a lot of killing you'd get a lot of zombies. Of course they'd have to already have some random packs of zombies in there but I don't know- sounds like a good idea....
