In gameplay, because everything is shut down in Lost Colony, it is hard to see inside. Eggman must shoot enemies, which causes explosions that create light that will last for a few seconds. The stage is also full of G.U.N. enemies and has an area that is practically a maze, where the player has to find the way to the floor above.
This section requires an expansion.
Level Up Item
The Jet Engine Level Up Item is found here. It is on an upper level of the stage which can be reached by jumping up containers. The Jet Engine is required to complete the stage.
Collect 100 rings
The player should pick up every Ring along the path. Firing at everything ahead can be helpful, but the player must take care not to run into the explosion radius of dynamite. When the player reaches the room where the Jet Engine was, they should take a moment to pick up the two Item Boxes (one is the balloon and the other is beneath a Container south of the center column.
Find the lost Chao
The player should begin by heading for the edge of the first catwalk out in space, and a platform hovering just below on the right can be seen. They should jump onto it to be elevated to another short catwalk with the Ancient Ruin at the end, where they must play the Mystic Melody. A series of platforms will appear which lead to a door, and the player must walk across the platforms, where they will come to a large gap with yet another low-set door positioned on the opposite side. They must Hover across and blast the enemy that appears while in midair to unlock the door. The player then must walk through one last door to find the lost Chao.
Reach the goal within 3:30
The player should keep firing to clear the path of any unseen enemies while they progress. If they are trying to score an A Rank, they must take a little extra time to lock onto and destroy as many enemies as possible for extra points.
Clear Hard mode
For this mission, the Large Cannon is required. The player should be careful when locking onto the explosives, as some of them blow up sections in the stage. To open the third room, the Wooden Containers have been replaced with a stack of Iron Containers and Indestructible Containers. The player must destroy the Iron Containers and jump to the top of what is left, then hover along the Rings to another stack of Containers, and from there to yet another stack of Containers where the Switch is.
In the Jet Engine's room, the player should walk forward slightly and then go to the right. From there, they will see two Indestructible Containers stacked on top of an Iron Container. They must shoot the Iron Container to drop the Indestructible Containers, which will form steps needed to reach the platforms above.

After the first Point Marker, the first Chao Container can be found in the left part of the right edge of the square room.
After the first Point Marker, the second Chao Container can be found in the room with the green energy fluid, precisely between the two elevators at the beginning.
