Skate is the closest thing to skateboarding without actually putting your feet on a board. With innovative controls that take advantage of the dual analogue sticks, the power of the next gen hardware, and the ability to sculpt tricks that define your own style, skate delivers an authentic boarding mecca like no other videogame. Individual style combined with physics-driven animations promise that no two tricks will ever be the same. And there's plenty of room to pull off those tricks-San Vanelona challenges you to explore, find, and own the best spots. You can even capture footage to create and show off your style with friends across the world-because without footage, it's fiction. Get ready for all the fun, creativity and culture of skateboarding without the hours of practice, broken bones, and hospital visits.
