I couldn't manage using arrow keys with the mouse -or at least, not on a laptop where the arrows are in the bottem left corner. But anyway I'd find it easier to bind stuff around WASD. (I don't play shooters much at all though...) Arrow keys are for much simpler, old games or flash game stuff.
Off topic a little, but did anyone else know that Tribes 2 is back, and for free! I never really played it much but it struck me as a very awesome game. Really amazed me because I was joking to the guys in my dorm (who have got me to start playing Halo) that I find all the guns far inferior to the spinfusor. So then I had to go Google/Youtube search for Tribes (they hadn't heard of it) when I discovered that apparently just a few weeks ago a public, free download or something was released -tribesnext I think. Just wondering if anyone here has heard of it (or cares).
