The game is divided into Adventure Fields and Action stages, similarly to the way done in Sonic Adventure. Action Stages are the basic playable stages for every character. Not every character has access to every level in Story Mode. Each Action Stage is differently structured for each character, in order to serve their gameplay mechanics. Action Stages usually take to 7:00 to 13:00 minutes each and can be accessed either from the Adventure Field itself, where it is located, or from the Menu. All Stages are listed here.
Adventure Fields work the same way as in the original. They are now vastly larger. They give the player the opportunity to explore and interact with various other characters. Aside from having the Action Stages, Adventure Fields contain various hidden prizes and items such as mission cards, Chao Garden items, Emblems, upgrades, easter eggs and bonus features. They are 4 in total. These are the following:
- Central City, a busy, city-themed Adventure Field and the main Adventure Field of the game. Sonic's story begins in this Adventure Field. It features large skyscrapers, shops, the train station, the beach, a hotel, a casino, the G.U.N. headquarters, Tails' Workshop, Prof. Pickle's laboratory and lots of other areas of interest.
- Angel Island is the largest of them all. It retains some of the sections from the original such as the train station, the jungle and the waterfalls. It features all of the Angel Island entirely, along with the ancient ruins of Teotihuacan, the mountains and various other different locations such as caves, underground mines, Finitevus' headquarters, the Mysterious Cat Country's village and others.
- E.G.G. Metropolis, an island where most of it is inhabited by Dr. Eggman's huge utopia. The other half of the island is covered with a dense jungle and a peripheral beach. Most of the stages are located in Eggman's base. Notable locations include the Main Tower, the beach, the airport and the bridge.
- Blue Ridge Zone is actually a suburb of Central City and specifically that suburb that was devestated by Chaos back in Sonic Adventure. It features various significant locations such as the Dragon Kingdom, Espio's homeland, Albion and the Greyhorn Alliance's mountain.

For Silver and Team Chaotix, the level changes drastically. As it takes place in the bad future, the stage is darker, the skyscrapers are even taller and are made of black mechanical components. It has a dystopian atmosphere. There are floating cars and the level mostly takes place in the sky. The artificial island with the beach resort is also changed. It takes place during sundown.

Lost Paradise is a stage very similar to Lost World from the original. It is Sonic's 10th level, Knuckles' 2nd level, Silver's 6th and Shadow's 19th level.

Some of the sections of the level feature dark pits, chambers filled with enslaved Echidnas, corridors and red carpets with lanterns. Nocturnal Haunt appears to also have a section as a research facility where Dr. Finitevus does experiments on Echidnas. However, in Silver's story, Nocturnal Haunt is much more different as it takes place many centuries before. It does not have that gloomy and dark atmosphere and does not resemble a techno fortress but instead is more like a fortress built inside of a mountain, made of stone. There are also waterfalls and vegetation instead of the lava river. There are no Dark Legionaires as enemies but King Ophis' stane minions.The stage's music is Black Comet .
Huge Inferno is Albion consumed by fire and destruction. It is situated in the Blue Ridge Zone. The level probably takes place inside the characters' minds as it is set in the past when Dr. Finitevus allied with Dr. Eggman and bombarded the entire city, wiped out completely the entire population of the city. The stage bares some similarities to Crisis City from Sonic 2006, except that it takes place on an ancient city. The most common hazard here is obviously fire.

Echidnapolis used to be the second largest Echidna city in antiquity located in the Angel Island.

The time between the events in The Chronicles of Sonic the Hedgehog: Rise of the Heroes and this game, the Echidna Tribe from Teotihuacan managed to rebuild and recolonize the city, operating normally. However, in the game, Dr. Finitevus conquers the city and enslaves all of its population, forcing it to rebuild the city in his own desire. Hence, the level resembles more of a dark, dystopian city. Some of the parts of the level feature tall towers and structures, seemingly untouched by time. However, as the level progresses, the player ends up in the centre of the city, which has been altered and reconstructed with black, cybernetic components with powerful lights. The towers are also much taller and thicker. The level takes place during night time for some characters and even in the sky.

The stage, therefore, takes place in a warzone in Old Megalopolis where the G.U.N. forces are fighting against Eggman's army with heavy infantry, tanks and airships. The navy can also be seen at some sections of the level. The ruins of Old Megalopolis are not covered in vegetation now but are ablaze.

The Air Winds is a race of enormous flying creatures, blue in colour and resemble whales with large fins. They travel the skies and pass through various locations such as from the Angel Island.

The stage is very long and is the only one in Sonic's storyline to have 2 Acts, although when selected from the Menu, both Acts are fused together. The player starts off from a forest, which then becomes a dense jungle and afterwards the player enters a valley with an ancient fortress, most of it ruins. As the player progresses, he ends up in Eggman's excavating site and then continues again to the ancient city until he reaches a road enclosed by two mountains where a fortress is built.

The first level in the Final Story, it takes place in the ships of the navy of G.U.N.. It is a stage very similar to Great Guns mentioned above, since both are located in the same place. There are, however, some minor differences. The sky is dark red rather than blue. Most of the stage takes place on the interior part of the ships rather than the exterior, which is armed with many security cameras, laser turrets and G.U.N. drones. The main difficulty here is to get passed the laser shooting cameras. It also features various loops, sealed gateways and corridors. As Sonic and Shadow, their stage segments are very fast and have to get passed through multiple obstacles that will hinder your way to Dr. Magic's cell. As Silver, you will mostly have to battle G.U.N. drones to open up gates, activate switches and bridges. Tails' segment is quite short and easy. There is no Goal Rings for this stage, instead, you will have to reach the cell where Dr. Magic is being held. The stage's music is Cannon's Core.

Gamma, Tails, Amy, Rouge, Team Chaotix, Silver, Big, Julie-Su, Shadow, Omega, Knuckles, Cream, G.U.N. Soldier, Blaze, Sonic and Fang. Each hero will head to one of the defense units and activate them. The defense units look like ancient, technological pillars. Once activated, they will shoot a beam upwards in the sky. This in turn will summon the ancient, mechanical soldiers, the guardians of the Angel Island the Echidnas had built, from the ground. Also, ancient turrets, cannons and even huge spaceships will rise from the ground and target the enemy.
As for the description of the stage. Fallen Angel, as stated above, takes place on the Angel Island. Recognizable segments from the Adventure Field are also present inside the level. Each character's version of the stage takes a different route, but is more or less the same. The entire Angel Island is falling apart. Large pieces of the island begin to disintegrate and fall into the ocean, so you have to watch your step. You will encounter many obstacles in this level such as Dark Legionnaires and Dr. Eggman's robots. Nevertheless, the ancient soldiers of the Angel Island and G.U.N. will be on your side and will not damage you. There are huge, ancient spacecrafts floating in the sky where the player will occasionally pass from. Some segments also feature the inside of huge, collapsing temples, water segments, paths with lots of vegetation etc. It is an apocalyptic stage.

His segment of the level features multiple enemies such as Dark Legionnaires and Eggman robots. After you pass a checkpoint, Big will continue. His segment features many small lakes and collapsing waterfalls where Big must use his fishing rod to open up switches and activate bridges. Finally, you proceed as Sonic in a very fast part of the level. It features multiple rails, falling platforms, floating ruins and speed relying sections. After a certain point, you will find yourself inside a huge, spherical chamber where the walls start collapsing and ancient spacecrafts detach from them. As Sonic, you will be able to get on board of some of these flying spacecrafts. There are also some bizarre, ancient switches that change gravity. And to make things worse, there is a time limit before the entire island collapses. The inside of the Angel Island seems to be built out of a very peculiar ancient technology making the level resemble a huge, ancient weapon hidden inside the island to make it impenetrable. Your goal is to follow Locke to the core of the Angel Island with the Master Emerald. The stage's music is Chaos Angel - Modern Remix.

List of Bosses
- Egg Viceroy - An ovoid shaped robot with 2 arms and a cockpit where Dr. Eggman sits in and pilots it. It does not have legs but floats just like Diablon from Shadow the Hedgehog. It is of orange colour. Its basic attacks are laser beams, bombs and other projectiles while it also uses its arms for close combat. It does not have any specific weak spot so hitting it anywhere on its torso will decrease its life gauge.
- Egg Chamberlain - Very similar to the Egg Viceroy, almost the same mech with red colour and more upgraded. This means that it is more powerful and deals much more damage. Its attacks are pretty much the same as the Egg Viceroy's. It is fought in the Sly Squadron level for most characters in Story Mode.
- Egg Aura - The Egg Aura is the same robot as the previous two, though highly upgraded. It is heavily armed and equipped with 8 Albion artifact. It resembles an ancient astronaut. It has a large torso with shining blue layers of energy on it and with the artifacts attached to its centre and various energy rings made of hieroglyphics orbiting it; two large arms and a head, where the cockpit is. It doesn't have legs so it floats using a blue energy that surrounds it. It has some attacks from the Egg Viceroy and the Egg Chamberlain as well as the ability to fire laser beams and energy using a scepter in one hand and another bizarre ancient instrument in another. It is fought on a spherical table with collapsed pillars around it, as well as platforms. Egg Gunners and Egg Pawns are around it, guarding it and will try to attack the player.
- Egg Acari - As its name states, it is a large mech resembling an actual acari. It has long, slender legs covered with a spiral metal that charges electricity and allows it to jump very high and rapidly. Although its torso is bogus, its is very fast. It does not use any projectiles and its main way of attacking is by charging on the player. It may also walk on walls and on the ceiling. It also has the ability to lay mechanical eggs which release Egg Pawns and Egg Gunners.
- Egg Shockmaster - A typical of Dr. Eggman's robots. Its key ways of attacking is by lightning attacks and electric shockwaves. Its weak spot is Dr. Eggman's cockpit.
- Egg Statue - Dr. Eggman does not pilot this one. Instead, it functions as a guard for the Tropical Sanctuary stage. It is very slow but its attacks can become very difficult to dodge.
- Magic Paladin - This one was constructed by Dimitri by using metal components from Dr. Eggman's robots. It was then used by Dr. Magic as a means of acquiring the Golden Epics. It resembles a paladin, as its name suggests. It wields a scepter with which it shoots projectiles. It is fought by most characters in story mode since Dr. Magic is one of the major villains in Silver's and Team Chaotix' storyline.
- The Magician - An upgraded version of the previous; it is piloted by Dr. Magic and was created by Dimitri using metal components from Eggman's robots.
- The Wizard - An even more powerful version of the previous two, the The Wizard is mostly fought in the final levels of the characters' storyline due to its high difficulty and needed strategy to defeat it.
- Beast of Xenin - A large, vicious, dog-like creature controlled by Xenin. It has spikes, claws, horns, cybernetic implants and chains. Xenin stands nearby on top of a platform and cannot be damaged but will not attack the player.
- Xenin - Xenin is a very simple Boss. He fights using mostly his blaster and other firearms although he does engage on close combat.
- Dark Legion Squad - This Boss is very similar to Egg Carnival and Egg Storm from Sonic Heroes. You basically fight a herd of Dark Legionnaires with all kinds of weapons. Although you can select your character here, power-type characters are preferable.
- Dr. Finitevus - He uses his magic powers to attack. He may also teleport using his rings or teleport the player near him to attack him.
- Dimitri - Dimitri is fought only in Glyphic Babylon. He has attached his head into an enormous robot that looks like a mantis. It attacks using its razor sharp claws. It does have some projectiles as well. The player can only damage him in his head, which is his weak spot. This design was first seen in the Archie comics.
- Enerjak - Dr. Finitevus after having acquired the Enerjak suit. He is fought twice. Once in Knuckles' storyline as the last Boss in Echidnaopolis and in the Final Story again by Knuckles. In Knuckles' story he is fought inside an ancient chamber with large, blue pillars with hieroglyphics. He flies and uses his scepter to shoot projectiles. As Knuckles, the player can only injure him by harnessing the powers of the Sacred Treasures of the Brotherhood of Guardians.
- F-36 THUNDERBIRD - A G.U.N. battle drone. It resembles a bird with large wings. It is piloted by a G.U.N. Soldier and the cockpit is located in the forehead of the machine. It is very similar to the Blue Falcon and Heavy Dog from Shadow the Hedgehog.
- G-76 BLACK SCORPION - Another of G.U.N.'s battle robots, it is much stronger than the previous version and is fought only by Shadow, Omega and the G.U.N. Soldier John Washington in Genocide City serving as their last Boss. It is piloted by Hugo Brass. It is fought in the rubbles of Genocide City. It uses many weapons to attack such as rockets, missiles, laser beams and the particle beam cannon. Its weak spot is its head.
- King Ophis - An enormous, green snake with a crown on its head. It serves as one of the main antagonists in Silver's story and is fought only by Silver in his storyline. King Ophis is the serpent king of the underground, chthonic kingdom of the serpents and every 7 years, it feeds on royal blood according to a very ancient tradition. It is fought in its lair. Its main attacks involve close combat with its body. It also summons smaller snakes to help it repel Silver's attacks. Hitting it anywhere on its body will damage it.
- Character battles - Character battles are the same from Sonic Adventure and Sonic Adventure 2. They are very easy to defeat. These are Sonic vs Metal Sonic, Sonic vs Knuckles, Tails vs Fang, Julie-Su vs Fang, Omega vs Gamma, Espio vs Metal Sonic, Silver vs Metal Sonic and Silver vs Blaze.
Final Story Bosses
This Boss is fought in the stage Final Fleet. It is piloted by Metal Sonic. The Boss is battled with every character except Sonic, Knuckles, Shadow, Silver, Metal Sonic and Big. Its design is based off the previous Bosses Egg Chamberlain, Egg Viceroy and Egg Aura, almost being a reconstruction. Its attacks are way more powerful that the formers.
This Boss is basically the same as the one you fought previously in Knuckles' storyline, with some differences. He is fought on a porch outside the Nocturnal Citadel with the Angel Island in the background and Argus' tentacles from above. His attacks are stronger but can be countered by using the Sacred Treasures of the Brotherhood of Guardians correctly. He does not have a weak spot, so damaging anywhere in his body will lower his Life Gauge.
You play as Super Shadow and Super Silver. Your task is to fly around the Nocturnal Citadel and destroy its cannons, shield barriers, troops and turrets. You can switch between Super Shadow and Super Silver. Shadow is faster and uses his Chaos Spear. Silver is more defensive and slower. He can use is psychokinesis to stop incoming projectiles and throw them back at the fortress. Remember to collect as many rings as you can. You do not lose rings when you're hit but you automatically lose 1 ring each second.
The Albion Thaumaturge was the most powerful war machine created in antiquity using the Albion technology by the Echidnas for the Forgotten War against the Nocturnal tribe. Now, it has been reawakened by Dr. Eggman and has invaded the Angel Island, causing massive destruction and eliminating every Echidna on the island. The Albion Thaumaturge is an enormous, titanic robot nearly 500 meters tall. It has the 9 Albion artifacts attached to its chest from the inside. As Super Sonic, you control another titan, which was built by the Echidnas in attempt to counter their original creation when time was to come. Your titan is slightly smaller. Your attacks include punches and a laser beam, which needs to be charged. The entire battle takes place on the Angel Island, while the sky is dark red and covered by Argus' monstrous tentacles. You can also grab certain objects such as nearby spacecrafts, pillars and even mountains to throw at Eggman.
As the Final Boss of the game, you take control of Knuckles as Enerjak. The battle takes place in the dark skies above the Angel Island. You must use your Sacred Treasures of the Brotherhood of Guardians, which have been upgraded to attack Argus. Throughout the entire battle, only his huge tentacles can be seen protruding from a blue portal. You will have to attack them in order to lower his Life gauge. Argus will only use his tentacles for attacks. For instance, he will grab floating remnants of the Angel Island and throw them at you, shoot laser beams, summon large boulders from the island below or just strike at you with them. Since the Enerjak is not a super form, you lose rings only when you take damage. The music for the Final Boss is 160 BPM.
