Gigan Rocks

"Plummet from the peak of the mountains where the shooting star legends were born."

- In-game description

Gigan Rocks is a course in the Heroes story of the game Sonic Riders: Zero Gravity. Knuckles is pitted against seven SCR-GPs to get to the finish line first.

Overview
These ancient ruins are built on and in a large mountain. The course starts with two large jumps, the first one having shortcuts for every type leading off of it (the Power and Grind shortcuts are accessed through either wall route of either side from the first jump. After these jumps, a turn leads to a cave, with yet another jump, that takes the racers inside the mountain.

Once landing inside the mountain, there's a Power shortcut for Bikes and Wheel gears and the course's only Spring shortcut if the character is on-foot/Attack mode. After a turn, the player must go to a stretch of course that rises as the racers ride on it until it's going straight up (this is the best time to use Gravity Dive). At the top of the stretch is another jump. The racers land outside near another Power shortcut. There are also grind and air ride shortcuts, but the latter can only be access if another character in front has created a slipstream path. There's also another shortcut that can be access via the same slipstream path that can be used by any gear type. After a sharp-turn that can be avoided if the racer used any of the shortcuts mentioned, there is a quick stretch of land that leads to the finish line.

Musical Themes
The music played in this course is entitled "Sealed Ground". The music selection has an Oriental theme to it. It is also the first piece of Sonic music that incorporated the use of a didgeridoo.
