After making it to the President's limousine, Sonic and Tails manage to track Dr. Eggman's location, the Space Colony ARK. Sonic assures the President that he'll stop Eggman as soon as possible and he and Tails leaves the limousine. Later, Sonic, Tails, Knuckles, and Amy reached the desert, where Eggman's base is located. Knuckles mentions how he also saw Rouge in that location. Tails volunteers to head towards the pyramid to find the entrance to the base.
This is a Mech/Shooting stage, which has Tails progressing through the desert to reach Eggman's base. The stage is surrounded by sand, which he must be careful not to fall into, as the machine will sink due to its heavy weight. Throughout the stage, Tails will be traversing through the many structures that are filled with GUN forces as well as Eggman's robots. There are occasions where Tails must shoot the dynamite in order to lower some platforms, allowing him to progress towards the Goal Ring.
The upgrade for Tails on this stage is the Mystic Melody, which is used to uncover secrets. This item is found around the halfway point. The Bazooka from Eternal Engine is required, as the steel crates on this stage prevents you from accessing the Mystic Melody. This item is required for Tails stage's Mission 3, to locate the hidden Chao.
