its a good game and you dont actually have to be stealthy i myself have gone through to leval 4-2 without ever using the L or R buttons and they control crouching, rolling, walking and blocking and i know this because those buttons are brocken so i have been non stealthy all this time and havent been able to finish it because i cant get passed that damned well tunnel were you have to crouch to get through because my stupid ds wont let met bring my head down any way once i borrow one of my freinds ds's i will finish the game and be happy
