Following the third checkpoint, in the area with two Gun Beetles and several Black Arms, a key can be found on a platform to the left within a Wooden Container.
The key can be found in a locked container just ahead, which is opened by defeating all nearby enemies.
During the first Air Saucer segment, the player must take the ramp on the left to reach the upper path.
The first key can be found in the Wooden Container right in front of the first Jump Panel.
The following weapons can be found in Prison Island: The neutral path sends Shadow straight to the Goal Ring near the end of the stage. Meanwhile, Charmy Bee (on behalf of Vector) asks Shadow to help him look for five top secret disks. He very quickly runs into Doom's Eye, who gives Shadow the usual goal of destroying the human military presence in the area. He is then treated to some flashbacks of his cell on the island, raising yet more questions about his past. Shadow the Hedgehog uses Chaos Control to teleport to the remains of Prison Island in search of another Chaos Emerald. Eggman's bomb caused toxic waste to flood the rivers in the area, and plant life has grown on many of the structures. Prison Island in this game is what remains of the island that was partially destroyed in Sonic Adventure 2.ĭr.
