Final Chase is the fourteenth stage in the Dark storyline of Sonic Adventure 2 and the fourth and last stage playable with Shadow. It represents Shadow's run through the ARK's underside to intercept Sonic after finding out he's alive and heading towards the Eclipse Cannon. It is the equivalent to Sonic's stage, Final Rush.
After finding out that he may not be the real Shadow and that Rouge is a government agent, Eggman informs Shadow that someone is headed for the Eclipse Cannon. Shadow immediately heads out to destroy the intruder.
This stage consists of numerous rails but the main gimmick of this stage are "spinning drums". These drums have a magnetic pull that draws Shadow to them. They only allow one direction when running on them: up or down. Some parts of the stage completely consist of these spinning drums.
Level Up Item
Shadow's Mystic Melody Level Up Item can be found here, which allows him to activate Ancient Ruins. It is on a small platform at the highest point in the green cylinder area.
Collect 100 Rings
There are plenty of Super Rings scattered all over this stage. The player must avoid attacking as many enemies as possible to lessen the chances of losing Rings, and beware of the Meteorites near the spinning drums.
Find the lost Chao
After the sixth Point Marker, the player must navigate a series of horizontal spinning drums until Shadow reaches a Pulley. They must then use the Pulley to reach a vertical spinning drum and climb it to the top. When the player gets there, instead of using the Spring, they should instead grab onto another Pulley which will lead to a platform where an Ancient Ruin is. They must then play the Mystic Melody to make a row of Rings appear and Light Speed Dash across them to reach another vertical spinning drum. At the top of this drum is a Pulley that leads to the lost Chao.
Reach the goal within 5:30
Successful completion of this mission depends on how quickly the player can navigate the spinning drums. They should jump off of them at the earliest opportunity and skip over as many of them as possible. For instance, when going down a steep hill, the player can jump from the top of it and push forward on the Control Stick to skip substantial chunks of this stage.
Clear Hard mode
This mission is quite difficult for a couple of reasons. First and foremost, there are a lot more Artificial Chaos, and their tendrils have a much greater range. Secondly, there are now enemies waiting at the top of many of the spinning drums. Also, some of the spinning drums can now only be reached via short Grind Rails or floating Springs.
Chao Container locations
After passing the first Point Marker and climbing the first vertical spinning drum, the player will eventually come to a tunnel. Before going through the tunnel, they should drop down on the catwalk on the left and walk toward the screen until the first Chao Container appears.
After passing the third Point Marker, the player must look in front of the vertical spinning drum on the right to find the second Chao Container.
After passing the fifth Point Marker, the Chao Container can be found on the back of the platform. This location is positioned at the end of the section where the player moves across a series of spinning drums between the walls of the Space Colony ARK.
