Unique to its genre, Crush introduces a valuable new gaming experience that is wholly suited to the PSP system. Set within a complex, hypnotic 3D world, players will use the game's unique crush mechanic to "crush" the environment and transform it into a more simplified 2D platformer. Once flattened, players will utilize the 2D space to move to new areas to solve otherwise impossible challenges, and unlock secret items that were previously unobtainable in the 3D environment. Players will then "uncrush" the 2D environment and return to the 3D world.
