I installed patch 1.3, and things are working fine, so far. The bots are using the link gun beam A LOT, just like they did in UT2k4. An annoying but fine change nonetheless. I also noticed the bots do attack the enemy core, but on select maps. Still, the crappy Leviathan AI on Serenity and Onyx Coast pisses me off. I can't count how many times the bots drove the Leviathan down the central gorge in Serenity or up the cliff face on the Axon side in Onyx Coast and remained stuck there. They also suck at the Leviathan's orbital cannon... BIG TIME.
Another thing I noticed, but I don't know if anyone else did... on Avalanche, when I captured the East and West cave nodes, the tentacle only deployed for a short while, and mysteriously disappeared. I didn't see the drainage on the enemy prime node at all.I tried it once so far, but I want to know if anyone else got the same problem.
It's good to see the map descriptions and previews have been fixed, though, as well as the map-specific (Searchlight, Morbias) issues being dealt with. I think Epic should focus on improving the bot AI vis a vis vehicle usage and prioritization of goals in CTF and Warfare maps.
