The Xbox 360 Controller borrows many design fundamentals from the Controller S. The left and right analogue sticks and triggers, the D-pad, and the face buttons are in the same spots, put together quite similarly. The start and Back buttons have been moved to the centre, flanking the new guide button, which allows access to your Gamercard and personal settings at any time. Removed from the older controller are the black and white buttons, which were oddly placed. Taking their place are the left and right bumpers..
