it will, it's just one of those things not high up on the priority list, it may return, or it may be replaced by a similar server style
I as well hope Zombies comes back it was brilliant it was the only server I use to play on and I had tons of money its where I met most of my friends. If enough players request it to come back is there a chance it will stay and not be replaced with a different thing and is there a chance that it will move up on the priority list?
