you can disable bosses...
that along with about 20 other configurable server.cfg options
That's one of the things I brought up before.
The new ZS was EXTREMELY modifiable.
Nox ZS is different than the one Snivy had on temp ZS. Temp didn't have those OP bosses.
Also I'm pretty sure nox screwed with all the zombie stats...speed, power, etc.
The version I had on the temp was what I felt was balanced, while taking into account what people compained about (eg; fast zombie pounce damage, headcrab attack cooldown, etc). I modified a lot of the default variables, including the damage and speed values for most zombies/weapons.
