They can also attach to the main console for use in handheld mode, or be shared with friends to enjoy two-player action in supported games. Each Lite/OLED - Left&Right has a full set of buttons and can act as a standalone controller, and each includes an accelerometer and gyro-sensor, making independent left and right motion control possible.
