[CryForMe]

I've really looked, but perhaps I just don't understand as much as I should.
I'm trying to develop a plugin that allows me to control the walking/running speed of the A.I. zombies on my server, but I can't even locate a cvar for it to begin. I thought with sm, I could use some sort of entity control on them to solve this, but I'm having trouble getting started. The game is Contagion. Any advice would be a great help.
