I see, thanks. That's the same case with Hitman 2 (move w/ left, aim w/ right), and they couldn't be changed. Drove me nuts, since I'm much more proficient with left-aiming thanks to Perfect Dark and the bow/slingshot in Ocarina of Time. It feels next to impossible to play when I use right-aiming, kinda like the whole "dominant eye" "dominant" arm" differences. It's like, "Here, now write in cursive using your opposite hand" -- WTF. The fact that the C-stick isn't designed for such a high degree of precision just makes things works (YOU DEVELOPERS WITH YOUR SINGLE SIDED MINDED DESIGN WAYS FRUSTRATE ME, JUST AS YOUR GAMES DID. But I love you Free Radical). As a result, I stopped playing Hitman 2 months ago after going thru only 4 missions.
I've come to the sad conclusion that I've lost any interest in Metal Arms.
