Zombies have their own Chat.
Humans have their own Chat.
Some ADVANTAGES
1. Well...for a big map(or maze) it would be good for communication between players. No more /whispering needed.
2. Quick and reduces user chats, commands = less spam(if system loads chat for each group)
3. Zombies can ragechat.
Anyway, hope you like the idea.
