Load times are painfully long. As far as I can see, there is no menu driven bots like in UT or ETQW. I've not tried starting my own server and doing bots that way. With the developer commentary turned on, one of them talks about the maps. I think he said 12.
The Character models look really good. The sound skips allover the place on my system for some reason, much like it did when Valve introduced that bug not long after the release of HL2. The maps themselves have some cool light/shadow features.
