The Kami's Lookout thing is something with your video settings. It's day time on my computer. This has happened to me and my friends when playing AvP2. We go to a day time level, and on some computers it's night. I think it has something to do with the "sun" being the source of light on the level, and some computers don't know how to work it. I know, that probably sounds kinda silly, but it's the only thing I can come up with.
