What❐is❐Dual❐Play❐mode?
❐ ❐
When playing a 2 player head-to-head game with a game console, such as
Playstation, XBox and Wii, users used to play the game with the screen divided
top and bottom or side by side.
With Dual Play mode, each player can enjoy the game with a full screen.
To play in Dual Play mode, the Dual Play glasses (type A and B) are required.
If your model does not include the Dual Play glasses, please purchase them
separately.
