Well there is sortofa zombie mode in ac. Its a script by razor and it works really well. Here it is:

[SELECT ALL] Code:

infect = [if (> (listlen $arg1) 0) [alias infectmode $arg1]]
infectmode = 0
infection = [if (&& (= (curteam) 0) (= (alive) 0)) [changeteam; say "Infection mode enabled"]]
start_intermission = [saycommand /infect; echo "Will the next game be Infection? 1 for yes, 0 for no"]
bind MOUSE1 [if (= $infectmode 1) [infection]; attack; crosshairload]

If you really wanted to play in zombies you could host a private server and make everyone run this script, then disable auto team changes.
