I am well versed with UT3.
What exactly are you trying to do overall with your game/mod Crusador? In my experience, if you are trying to do anything other than Deathmatch, you might as well forget it. I'm not saying it's not possible, on the contrary Unreal is a very versatile engine. But doing other things with it requires coding.
I have also done extensive research on advanced bot pathing techniques using Kismet. I tried spawning bots, have some run at you and follow you while having other run to a position and hold there. The result was a trade off I couldn't figure out because, well, right now there is hardly any documentation on advanced Kismet stuff.
You may know that you can rename your little DM-whatever and when you test it you can get enemies to spawn. If you've set up paths, they run at you to attack.
However, if you spawn them in via a triggered event, they lose all sense of intelligence and don't follow the normal seek and destroy AI. They do however listen closely to what sort of direction you do give them.
I have a large Kismet try working, trying to get it to work, but never could. Like I said, it's just so undocumented right now it's tough to figure out.
One other kick in the teeth UnrealEd gives you is that it is very difficult to load your own custom mesh for the player or for bots. It's easy to get animations imported, as long as they are not playable or bots. Again it requires coding.
My advice to you if you are doing something other deathmatch with the preset characters/bots is to you Source SDK. It's free and it is very well documented by the community.
My opinion on the matter might change after these two books come out:
http://www.amazon.com/Mastering-Unreal-Technology-Introduction-Design/dp/0672329913/ref=sr_1_3?ie=UTF8&s=books&qid=1244604822&sr=1-3
http://www.amazon.com/Mastering-Unreal-Technology-II-Advanced/dp/0672329921/ref=sr_1_4?ie=UTF8&s=books&qid=1244604822&sr=1-4
But even then, the chapter lists don't indicate any advanced AI techniques.
The best resource I can point you at for learning UT3 is
http://www.ut3modding.com/index.php?page=31 They have many, many hours of free video's here. They are very good. But again, it's deathmatch centered.
