The main differences being some textures and the main menu in DeepBrick's video not being present, a debug screen in its place. Due to the found version being in its alpha stages, there are a few differences from the clips leaked previously. It was emailed to a fellow admin of BioMedia Project 'JuniorMasterBuilder' by an anonymous source, with Vahkiti's co-host of his YouTube Channel speculating on-stream that the source may have been an ex-Lego or Saffire employee. On February 10th, 2018, YouTube user Vahkiti (host of channel The Beaverhouse, and co-admin of the BioMedia Project content archival fansite) streamed a copy of an Alpha build of the game. Several pieces of music, all the cutscenes, and a complete gameplay video of what is playable have been uploaded to YouTube, as well as some 3D models being released, as a result of this leak. DeepBrick gave several of the game files to RedQuark, who leaked some of them to the public. DeepBrick was at one time in contact with Mask of Destiny user RedQuark, who was trying to locate the game. There is only one confirmed development disc in existence owned by a user named DeepBrick. There is also rumored to be 10 beta discs of the game floating around in the hands of collectors and former Saffire employees, but this is a disputed rumor. In 2001, there was to be a beta test of the game that people could sign up for, but it is doubted by many that the test ever actually took place. The Vahi ended up being distributed as part of other promotions, and it is speculated the printable instructions were worked into the Master Builder Set, released as a LEGO Shop at Home exclusive in 2002. The developers have since stated that this was a very simple bug and could have been fixed within a week, but since the funding wasn't there, the game was instead cancelled. Since Onua's stage is the first level in the game, it's impossible to progress any further. However, the developers ran into a problem in Onua's stage: there was a section where Onua had to jump down several platforms, and one of them was too low, causing Onua to automatically die upon landing. The game would also include building instructions for several models that could be printed out. A physical plastic mask compatible with the toys, the Vahi, Mask of Time, was meant to be packaged with the game.

Toa could use their Elemental Powers, explore eight-game environments, and collect five masks each. The storyline was meant to pick up where the Game Boy Advance game BIONICLE: Tales of the Tohunga/ Quest for the Toa left off, be a sister game to the Mata Nui Online Game, and be a prequel to the 2002 BIONICLE storyline. The Toa traveled across the island of Mata Nui looking for the Great Kanohi Masks of Power, hoping to use them to defeat the evil Makuta (later named Teridax) and awaken the Great Spirit Mata Nui after which the island was named. In the game, the player would control the six Toa (later named the Toa Mata): Tahu, Pohatu, Onua, Gali, Lewa, and Kopaka across the six main levels.
