Cosmic Fall

Cosmic Fall is one of the six final stages in the Shadow the Hedgehog game. It takes place on the Ark, which is apparently collapsing, thanks to the Black Arms. Many platforms are simply floating as they fall, alarms are blaring everywhere, and to top it off, there are only 15 minutes to finish the stage.

Stage Number
Cosmic Fall is one of five Stage 06s.

To Reach
Cosmic Fall can be reached by completing the Hero mission of Iron Jungle, the Normal mission of Space Gadget, or the Normal mission of Lost Impact.

Story
Either gun down Robotnik's blimp in Iron Jungle, flee to Prof. Gerald's lab in Lost Impact, or obtain the Chaos Emerald in Space Gadget to arrive at Cosmic Fall. In the level's opening cutscene, Shadow Chaos Controls straight into a confrontation with the GUN Commander, who reveals the reason for his antipathy against the black hedgehog - he witnessed the Ultimate Lifeform's creation by Gerald and Doom 50 years ago. Shadow dodges a bullet from the Commander's own gun, but he promises to submit to justice if it turns out he really was responsible for the death of the ARK's population. Shortly after starting the level, Doom's Eye asks Shadow to retrieve a Chaos Emerald located in the ARK's power plant. As they enter the first interior area, Vector the Crocodile makes a surprise entrance, desperately searching for the ARK's computer room. What objective Shadow chooses ultimately depends on what actions the player takes in the final room of the power plant. Fall from the doorway to the floor and you'll be forced to complete the dark mission. However, you can also Triangle Jump across breakable panels or Light Dash to an elevated platform on the other side, from which you can traverse one more section of crumbling debris before finding the computer room and completing Cosmic Fall's heroic mission. Go the extra distance to complete the hero mission and Black Doom manifests himself, A scuffle between the two ensues, with Vector fighting on your side, for what it's worth. Settle for the dark mission and Dr. Eggman pops up with his Egg Dealer, determined to stop Shadow from tarnishing his granddaddy's legacy.

Behind the Secret Door
A switch. Once activated the switch open a nearby door with an extra life and it also creates ring trails that are used to light dash through the rest of the stage. Very helpful when completing the Hero Mission and during Expert Mode due to the fact that it becomes hard to fall of near the end with the light speed dash.

Trivia

 * This stage led to one of Vector the Crocodile's most popular quotes, "Find the computer room!".
 * The name of this stage, 'Cosmic Fall', is a reference to the Sonic Adventure 2 level known as 'Cosmic Wall'. However, instead of Eggman climbing the outer rim of the ARK, Shadow is trying to survive as the colony falls apart.
