Mata Nui Online Game

The Mata Nui Online Game was the first online game on BIONICLE.com. It featured the Matoran Takua as the main character, as he traveled across Mata Nui, featuring such important events such as the coming of the Toa, the defeat of Makuta, and the awakening of the Bohrok. It was very popular, and an offline version was made available for download on March 2006-February 2009.

A sequel was made, the Mata Nui Online Game II, but it was glitch-ridden and wasn't as popular until a group call BioMedia Project help remove the glitches and made various of update on the offline game (with the permission from the team who created MNOG II)

It has since been removed from Lego.com & Bionicle.com.

Tahu's Arrival
The adventure picks up immediately after the events of BIONICLE: Quest for the Toa, with the player as an amnesiac Takua on the beach of Ta-Wahi. Almost immediately, he spots a large, opened Canister lying on the beach before him, with a set of large footprints in the sand leading away from it. Takua follows them into a field of volcanic rock, where he catches a glimpse of a tall, red-armored being, who then walks away.

Turning back toward the beach, Takua's attention is again redirected by a distressed-looking Ga-Matoran yelling for help.

Trapped Undersea
The blue-armoured Matoran introduces herself as Maku, and tells Takua that her village has been attacked by a vicious Tarakava, and she is the sole escapee. Having lost his memory, the Ta-Matoran has no idea what she is talking about, but decides to help Maku anyway.

Borrowing Maku's boat, Takua travels to Ga-Koro to discover that it has indeed been attacked and heavily damaged, but initially sees no sign of the villagers. However, he eventually spots a thin tube poking out of the water, with female voices issuing from it. The lead speaker identifies herself as Turaga Nokama, and tells Takua that she and the other Ga-Koronans had taken refuge inside a hut during the Tarakava's attack, but the Rahi had damaged the pump that keeps the hut afloat, trapping the Ga-Matoran underwater, with a slowly decreasing air supply.

To save them, Takua borrows a Lightstone from Nokama's Hut, and quickly locates the pump's missing piece at the bottom of the sea. He fixes and reactivates the pump, raising the Ga-Matoran's hut to the surface and freeing them... Right as the Tarakava returns for another attack.

Right as the reptilian Rahi is about to kill Nokama with a blow from its powerful arms, the Toa of Water, Gali leaps in to block the blow, and engages the monster one-on-one. After a brief duel, Gali jumps onto the Tarakava's back and "rides" it into the sea. Following a brief, unseen struggle underwater, the now-docile Tarakava emerges along with Gali, who triumphantly holds up a rusted, tarnished mask.

Return to Ta-Koro
As Ga-Koro is being rebuilt, Takua takes a boat back to Ta-Wahi, and decides to do some exploring in the area where he had first glimpsed Tahu. Eventually, he wanders into a shadowy, dangerous forest of burnt, dead trees, plagued by the howls of unseen monsters. As he continues tentatively through, he encounters a lone Matoran wearing red armor... and moving very, very slowly. He introduces himself as Kapura, and explains that he is "practicing." Eventually, Takua moves on, and re-discovers the volcanic village of Ta-Koro. Inside the fortress, he meets the Ta-Matoran's Turaga, Vakama. For some reason, the Turaga's attitude toward Takua is rather cool, and reveals that the young Matoran had been banished from Ta-Koro a while ago, for undisclosed reasons.

However, Vakama goes on to describe the arrival of Tahu, the red-armoured Toa that Takua had first glimpsed on the beach, and how the Ta-Koro Guard, led by Jala, had accidentally mistook Tahu for a Rahi, and caught him in their trap. Fortunately, Vakama arrived before anyone got hurt, and explained Tahu's presence. This, the Turaga told Takua, was a joyous day for the Ta-Matoran, but he also mentioned that he was receiving prophecies predicting the arrival of another unknown hero, of which he was uncertain...

Onu-Koro
Leaving Vakama's hut, Takua ventured from Ta-Koro into a large network of tunnels, which eventually brought him into Onu-Koro, an underground village lit by lightstones. After helping a group of miners access a cave filled with lightstone, the Ta-Matoran travels down a tunnel route marked "Le-Koro", only to happen upon a large group of Onu-Matoran digging a highway to Le-Koro. After talking with one of them, Taipu, the Onu Matoran successfully break through into the bright, verdant forest of Le-Wahi. Taipu, who has always dreamed of visiting the lush jungle, begs Takua to take him along on his journey to Le-Koro, and the Ta-Matoran is forced to accept. Taipu is ecstatic, but when he spots the tree village of Le-Koro, he is promptly abducted by a Nui-Rama.
