IAWtheseP -- bored me to tears at E3, wandering the same brown rooms and corridors. It's like they put the Rengoku team on an FPS. Enemies are cool, weapons are cool, but oh lord the visual tedium is physically palpable.
I enjoyed Ghost in the Shell: Stand Alone Complex in Bandai's booth more. Better level designs, better mission variety, and hey, a tachikoma tank buddy to do your dirty work.
Get used to the PSP FPS scheme of left analog to move, main buttons to aim, L to jump, R to shoot, and d-pad to swap weapons.
