Final Rush is the equivalent to Shadow's Final Chase and features many grind rails suspended below the ARK's underside. The stage is also abounding of Artificial Chaos and hornets making the stage more difficult to the player than the other stages in the Hero Story.
After Sonic was blasted off in a capsule that was going to explode in minutes by Dr. Eggman, Sonic uses the fake Chaos Emerald that Tails had given him to perform Chaos Control. He then warps onto the ARK in front of Knuckles, who had just finished looking for the Master Emerald. Sonic tells Knuckles that he is going to continue with his mission of putting the fake Chaos Emerald in the Core.
Level Up Item
Sonic's Mystic Melody is found here. To obtain it, the player must grind down the Grind Rail after the sixth Point Marker to find two small platforms on the left side along the grind. They should then jump toward the platform with a rocket. The rocket will take the player to another small platform. From there, they have to jump to the small platform with a Spring in front of them. The Spring will launch the player to a series of platforms, and on the top platform is the Mystic Melody.
Collect 100 Rings
There are plenty of Rings in this stage, but to collect one hundred Rings as quickly as possible, the player should try to jump onto the more difficult to reach rails and aim for as many Item Boxes as possible.
Find the lost Chao
After the fifth Point Marker, the player will stumble upon a long sole vertical Grind Rail with a Spring atop of it. This rail will lead to a platform that has two rails coming out from it. The player should take the purple rail which leads to the Ancient Ruin, then play the Mystic Melody there to make two platforms appear up ahead. They should then jump onto the second platform and grind up the purple rail in front of it. To gain some speed, the player needs to Homing Attack onto it. The player must follow the short path it leads to and play the Mystic Melody near another Ancient Ruin to make a row of Rings appear, then Light Speed Dash across them, grind down a series of vertical and horizontal rails, and the section where the lost Chao will be up ahead.
Reach the goal within 5:00
While grinding rails, the player should crouch to build speed. Additionally, the player should avoid stopping to attack enemies or go after Rings.
Clear Hard mode
The first Artificial Chaos encountered in the stage now attacks, so the player should jump from the rail and perform a Homing Attack on it, then another to home onto the nearby Spring and get back to safety. Additionally, some platforms are now farther apart, so the player has to use the Homing Attack on Item Boxes and vertical rails to reach them.
In the final room, there is a giant Weight beside two Artificial Chaos that cover the hole needed to get down. The player must destroy the Artificial Chaos on the right to reveal a switch that keeps the Weight suspended in air.
Chao Container locations
Towards the end of the stage's very first rail, there is another rail to the left. The player must jump onto it, and then onto a vertical rail ahead. From there, there is a platform above with a Spring that can be seen. The player should bounce from the Spring onto another platform that has a Dash Panel and another rail, then use the Dash Panel to grind up the rail and land on the other rail to the right. At the end of this rail is the first Chao Container.
The second Chao Container is tucked between two Wooden Containers on the platform just after the first Point Marker.
After the third Point Marker, the third Chao Container can be found among the containers on the platform before the long red rail.
