Bionicle: The Game is an action-adventure video game released in 2003. The game is based on parts of the movie Bionicle: Mask of Light and other parts of the Bionicle storyline. Initially, the game was supposed to make each Toa Mata, Toa Nuva, and the Toa of Light playable, but due to deadlines, much of the game was dropped. However, all of the characters are playable in the Game Boy Advance version.
The game follows the 2001-2003 storyline with only one obvious omission; the first part of the 2001 story, when the Toa first face Makuta, was cut out. However, many parts of the story were "reduced." The game begins when the Bohrok are attacking Mata Nui, and spends two levels depicting Tahu and Kopaka's battles with them. After that, the game moves on to Gali Nuva's level, in which the Bohrok Kal are introduced, and all defeated at once by Gali. In the storyline, Tahu Nuva uses the Kanohi Vahi, mask of time, to allow himself and the other five Toa to defeat them. Pohatu's level then depicts a "midpoint" between storylines; Pohatu is delivering the news that the Rahkshi have awakened to Onua. Onua then defeats Lerahk in his level by dropping a hub unit on Lerahk, Lewa fights Panrahk in his level, and Tahu lava-surfs after Kurahk, who has made off with the Mask of Light. When he catches Kurahk, the Mask of Light fuses itself to Takua, who becomes Takanuva (Takua Nuva in the game) and defeats Makuta, Lord of Shadows, in the game's final level. He transforms on Takutanuva and opens the door and awakes Mata Nui. The Matoran only make a couple appearances, none of which are very significant to the plot.
