I just downloaded Nexuiz, the first thing that I notice is that I can't aim up or down, just rotate my vision with the mouse. I tried +mlook in the console and that didn't do anything. I tried +klook and that works fine, but it is really difficult to play that way because there is no way to move forward. When the bots get decent and can aim when I can't, winning is impossible. Anyways it would be a decent game if I could aim. Is this fixable?

Try "m_pitch 0.022" in the console. There is a bug that sets m_pitch to "off" when you click "reset to default" in the Options/Input menu. (It fixed in the upcomming 2.0.1 release)

Thats probably it. I'll check. Thank you.
