Note. This will not work with U1. I compiled it with Botpack as an edit package. DERP!!!!
RC2, will work with U1 and UT. It will most likely also fix the errors inherited from the Fly code that occasionally cause the warnings in the log. (State TacticalMove. Function PickDestination craps....)
The default sightradius for the zombies is set at 8200, but if you use the SwarmSpawner mutator instead of the mutator included in the Zombies5 package, I think you can adjust that. (Haven't testing adjusting that specific setting yet,....)
