I've been looking to do this too.

I decided to hack up my own version, and it went terribly wrong (100% due to Zombie Fortress redux) being broken for ages.

Essentially:

Zombie Fortress: Set Blu's = Zombies, Red's = Survivors.
Class Restrict: Blu = Only Medic, Red = only engineer.
Weapon Restrict: Disable all for blu except melee.
Build Restrict: Disable Sentries.

In theory, I believe it would work perfectly, a bit hacked together but still would work, if damned zombie fortress was updated since 4 years ago... :/
