Sonic the Hedgehog: Bermuda Triangle

Sonic the Hedgehog: Bermuda Triangle is a platform videogame for Windows, Linux and MacOS systems. This game features a side story at Sonic the Hedgehog saga in which Sonic and co. must travel to the elusive Bermuda Triangle, in search for the all-new Titan Emeralds. It allows the concomitant usage of three playable characters, and the player may choose among THREE teams consisting of those three characters.

Plot
Two millenia ago, there was an island named the Bermuda Triangle, in which the Tiger Eye Clan stored the Titan Emeralds, a twisted version of the Chaos Emeralds with a dubious power. The Black Arms once raided the island and threatened the Tiger Eye Clan. Oceanus, the Tiger Eye Clan ruler, was killed off in battle by those dark entities, but Selena the Lynx, Hyperion's only begotten child and heiress to the Clan's royal mantle, resorted to the Titan Emeralds' power in order to drive the Black Arms away and avenge her deceased father, also costing her own life in process. From then on, her wraith provoked chaotic phenomena surrounding the isle. Years later, Dr. Robotnik discovers the island and the Emeralds, and sets up a base on it. Endymion, the sole descendant of the Tiger Eye Clan, sends a distress call to his acquaintance Shadow, who also enlists Sonic and co. for this mission to stop Robotnik at all costs.

Titan Emeralds
Just as mentioned above, the Titan Emeralds are a brand new resource in this game. The player must collect a minimal amount of Rings in order to unlock the special stage onto a checkpoint. This special stage is similar to the ones at the 8-bit version of the first Sonic the Hedgehog, except one must gather a certain amount of Rings in order to acquire one of the Titan Emeralds before time runs out.

Ultra Transformations
By collecting all seven Titan Emeralds from the Special Stages, all of the team members will have access to a more powerful form upon summoning the power of the Titan Emeralds. The mechanics of Ultra Transformation are exactly the same as Super/Hyper Transformations from other Sonic games.
