BIONICLE: The Legend of Mata Nui was a planned PC game to be released Fall of 2001. Developed by Saffire Corporation, it was canceled due to two main reasons: lack of budget and a glitch that would not let the player advance from the first level.
The player played as the Toa Mata exploring the island through 8 levels, using Kanohi and battling Rahi. The game features a huge emphasis on problem-solving. Due to a glitch, the player could not advance from Onua's level (the first one). This glitch was at a platform where the player was supposed to drop down to to complete the level, but it instead kills the player.
At least 8 very rare Beta CDs could be found in a few selected 2001 Toa Canisters set (these selected could be either the prototypes or the ones use during production uses) or those who own a beta copy of the game as most of the copies of the pc game and the development CD are currently property of The LEGO Group.
The LEGO Group was planing to distribute Masks of Time with the PC game but since its cancellation; the Kanohi Vahi were instead given away as promotions for BIONICLE at selected Walgreen stores in America and also other promotional events across the world in 2001.
