This is a preowned video game. It is guaranteed to work on your Game Boy Advance video game console and may not include a box or instruction manual. From renowned producer and game designer Hideo Kojima (Metal Gear Solid 2), comes Boktai, the first GameBoy Advance title to use sunlight to influence gameplay. Boktai's breakthrough technology is achieved through the use of a solar sensor on the back of the GameBoy Advance cartridge. When the solar sensor is exposed to sunlight, the game uses this information and directly changes the gameplay experience.
