Metal Gear Arcade is a reworked, networked, coin-op iteration of Metal Gear Online.
It has a special interface that utilizes 3D goggles and tickets to unlock jewelry and other weapons.
It was released in Japan on December 20, 2010. It was removed from many arcades due to a lack of popularity.
Speedrunners can access Metal Gear Arcade thanks to emulation.
