Its a pretty good idea, if you need help with mapping, I can help you. About the NPCs, I don`t know exactly if there is any NPC Streamer right now but, anyway, you will need a lot of functions like, making the zombies to take damage, wear guns, be smart and follow the closest target and, there`s a a main reason why you can`t use NPCs: If you make a NPC follow a player, if the player gets into the village/safe zone, the NPC will fly over the fences and this will make the safe zones useless if you don`t find a way to stop them from doing that.

Please tell me more about the project, it looks interesting. Best regards,
