I found my old psp console the other day and was wondering if there are any 'shooter' games out there that allows me to use the analog nub on the PSP as aiming or to move the camera.

For exmaple:

Gun: showdown, It allows me to aim using the *left analog nub* and i can walk using the triangle ,circle etc keys

Another is the Homebrew PSP Game Nazi zombies portable which also allows me to aim using the left analog stick.

*I wanna find PSP games that have this function, Many thanks*
