I remember a few years back that zombie servers was the place everyone liked to go to, just wondering if people still keen on zombie servers.
There were 2 types of zombie servers that were around
1: mass bots being zombies, get killed you become zombie.
2: No bots and only players. Randomly someone was a zombie and everyone else stays human. 1 Knife stab turns you into a zombie and there were 2 types of zombie maps being rotated, ZE (Zombie Escape) and ZM (Zombie Map). ZE has a goal for humans to get to/do to win and ZM were just camp maps, where you find a room or spot and camp and last the round time.
Of course #2 is the |IC| zombie server settings, which was popular but then admins started to tell everyone what to do and that was enough to make me stop.
Just a suggestion, maybe zombie mode isn't as appealing as it once was.
