I played a normal vanilla Quake DM game against one frikbot at skill 1 and won 15 to 5. My therapist and I are still working on helping me to cope with what happened on skill 3, but he assures me that, given time, the shaking should stop.
Basically, the frikbot won 15 to 3.
My greatest aggravation was that once he got a rocket launcher, I'd die every time I turned a corner. A human would notice a flash of movement or something and have to let the message from his brain order his hand to move and fire, but a frikbot has fired before that message even gets sent. It gets quite maddening.
That's why in Jeht & Ace of Nails I toned down the skill levels, giving bots worse aim and lower response delays with lower skills. Skill 3 was un-touched, though.
Anyway, I played on DM5 and the bot didn't seem to get stuck in the water AT ALL, which is awesome. He did occasionally get stuck on the door frame between the switch and the door that opens to the rocket launcher & megahealth, trying to run through the wall toward the switch. He also discharged in the water a number of times, but I'm thinking that was a calculated move...
He also got stuck a couple times coming out of the teleporter toward the Super Nailgun and yellow armor: he ended up in the corner on the right side of the door frame, as if trying to run straight toward the super nailgun or armor, oblivious to the wall in the way.
Playing in Skill 1 was enjoyable, but I won quite easily. Skill 2 seemed about right, and I'm going to need some practice before I can start winning again in skill 3. I can win in my own mods against FBXa in skill 3, but in normal quake my pride just got hurt real bad.
I'd like to test FBXb further, both in normal quake and a mod or two, probably in Jeht. I'll let ya know!
