Shadow uses Chaos Control to warp himself into an area that may have that (damn) fourth Chaos Emerald.

But then... He suddenly had some flashbacks. Some old memories returned to him. He somewhat recognizes this place as the area he was found in, but then captured and sealed into by humans, but can't quite from where or why.

Indeed, this is Prison Island, or at least what was left of it after Eggman blew it up. It's now a toxic wasteland of its former self.

You have three missions to choose from in this level:

Dark Mission: Team up with Black Doom and destroy all of the GUN robots in the area.

Normal Mission: Head for the fourth (damn) Chaos Emerald at the Goal Ring.

Hero Mission: Team up with Charmy to collect 5 Top Secret Disks.

I picked the Dark Mission, this time.

This necessitates taking different routes in order to reach the GUN Robots that can only be found on said routes.

The Dark Mission has the shortest length of the three on this stage, as the GUN Robots stop appearing right before the Normal Mission's Goal Ring.
