I hope they keep and improve the bots. There's nothing better than, when you're bored, fire up UT2004 and play an offline game with some bots. Not to mention that when you get problems with your internet connection or lag (a little too frequent in my case, since my ISP sucks; I'm changing this month), it's cool to be able to play offline.
The mod, by the way, looks great, especially for Beta 1. I think the gameplay is much more enjoyable in the UT2004 code than in Unreal 2, especially the veicules.
This one and Jailbreak should be in everyone's harddrive, when it comes to custom gamemodes.
