This stuff?
https://www.moddb.com/mods/quake3-hopperI didn't know about its existence, and I'm even a bit surprised about bot AI tweakings done through engine, as I thought the bot stuff was mostly gamecode-driven.
I haven't tried that, but considering it's in engine, I find it quite unlikely to have it working with OA, unless trying something like running baseoa as a mod within Q3...
