Sonic Emerald Quest OST - The Grand Eggship by Jarel "Arrow" Jones
5SRB2 is used here because it is the closest thing associated with Emerald Quest. I'm guessing this track is where the idea of Doomship/Grand Eggship came from, though it's still out there whether that level will even be made.
Sonic: Emerald Quest was a planned roleplaying game that Sonikku conceived as the next project for Sonic Team Junior after SRB2 was finished. It was never produced, but several design documents were written for it. The game was to feature three main characters: Sonic, Tails and Knuckles. Their storylines were planned to interact with each other, so that events that took place in one character's storyline would have impact if the player finished it and played through the game again as another character. The story revolved around Eggman and a cult known as the Dark Mobians attempting to summon an army of monsters to overwhelm the planet Mobius. Sonic's storyline would involve trying to stop Eggman and the Dark Mobians, while Tails would try to defend the planet against various assaults by the monsters and Knuckles would try to safeguard the Chaos Emeralds, which played a large role in the summoning pact.
The game would have featured a few of the, at that point, lesser-seen members of the Sonic universe, such as Mighty and Ray from the SegaSonic the Hedgehog arcade game and Bark and Fang the Sniper from Sonic the Fighters, as part of larger teams that the player could control. Designs were started for a few original characters, but they did not progress very far beyond move lists. No clear combat system was ever designed. Several possible engines were considered for the game, ranging from a top-down view to full 3D (likely derived from the SRB2 engine). However, shortly after SRB2 was moved to Doom Legacy, work on Sonic: Emerald Quest was halted and the project has since been canceled.
The only part of the game to be finished was the extensive soundtrack produced by Arrow, some of which would be added as part of SRB2's own soundtrack from Version 1.09 onwards. Other tracks have been used in custom modifications for SRB2 such as Blue Heaven and Acid Missile.
