Heyyo,
I'd have to say AImod. It seemed to be more smarter than bobots, but the last one I tried wasn't for the latest patch so it warped everywhere n' stuff, but since they released a new version, I bet it's for the latest patch, so give it a go!
bobots is good, but even on easy their aim's inhumain, perfect aim after 1 second...
The waypointing system is very basic on bobots, but the editing is hard. Couldn't figure out how to delete pathwaypoints, and it wouldn't save my waypoints (I'm guessing cause they were intergrated into the .pk3 file...).
My suggested place for RTCW files.
