Story

SA3Breakdown

The story features 8 characters, each sharing a similar story with different levels. Each pair of characters also has a similar gameplay style. Sonic and Tails both feature speedy "Get to the Goal!" missions. Shadow and Vortex feature shooter style gameplay. Blaze and Silver use their abilities (psychokinesis and pyrokinesis) to get through missions (Blaze having some treasure-hunting aspects as well). Finally, Knuckles and Rouge are Beat-em-up and treasure hunting rolled together. Each pair of characters eventually share the same stages together, and after beating all stories, the final story, which is just the battle against Centurion, is unlocked.

Sonic's story

Sonic and Tails are running after Dr. Eggman, who, as usual, is up to no good. This begins the game with the Vs. Eggman Mach Speed section, where Sonic and Tails must avoid the firing of the blasters attached to the back of Eggman's Eggmobile. At the end, all of a sudden, a portal opens and Sonic can't stop in time. Eggman sent Sonic to another part of the land. Introduced to Selmondi City, Sonic asks the people of the city if they have seen Tails. To his disappointment, Sonic had no luck. He eventually finds the entranceway to the zone the city rests beside: Cerulean Heights, a place with unnaturally blue grass. Reaching the end of the zone, Sonic encounters Eggman in his newest machine: A massive mechanical wingless dragon known as the Egg Drake, with a sharp point at the end of it's tail, bulky limbs, and two laser cannons on it's back. It didn't take long for Sonic to defeat Eggman. Once he defeated Eggman, a key to a gateway in the Selmondi City Adventure Area lands in the center of town. Sonic grabs the key and enters the gateway, leading to the Kelistona Island Adventure Area. Sonic finds a cave that leads to Emerald Mine, a cave system adorned with glowing green crystals that also functions as a zone. Sonic makes his way through the zone, ending up on the other side of the Kelistona Island area. Sonic then finds a tunnel under a lake. Going through it, he reaches Rapid River Zone. Since the water is too deep to climb out of, Sonic must allow the water to carry him down stream to a more shallow area. He must avoid Badniks and obstacles floating in the river. Once Sonic reaches the end, he encounters Eggman once again in his Egg Kraken, who has 6 tentacles that all end in a rapid fire blaster. After Sonic destroys the Egg Kraken, Sonic finds a warp platform that would allow him to travel back and fourth between the Selmondi City and Kelistona Island Adventure Areas. At this point, the player also unlocks the Chao Garden for all characters. Dr. Eggman flies his Egg Carrier over Selmondi, and Sonic dashes through Selmondi Highway Zone in a mach speed section. Taking a very risky jump, Sonic is able to grab onto the Egg Carrier and spindash through it's hull. Now within Egg Carrier Zone, Sonic runs through, destroying Badniks. Eggman is aware of Sonic's presence, and triggers several traps. After avoiding all the traps, Sonic arrives at the bridge, where he faces off against Eggman in his Egg Exosuit. He beats Eggman and the Egg Carrier begins to explode. As Eggman escapes, Sonic only has 6 minutes to backtrack to the hole he made in the rear (Egg Carrier Zone Act 2). As he leaves, the Egg Carrier explodes over Selmondi. However, Act 2 is not complete. Sonic must Homing Attack into the falling pieces of debris to destroy them before they crash down on Selmondi. A crystal falls, and another key arrives in the Kelistona Island area. Sonic warps back to Kelistona Island and obtains the key after grabbing the crystal in Selmondi. He unlocks a gate that leads to a portal. He is teleported to Station Square, just under the atmosphere. Tails, who was in the Tornado searching for signs of Eggman, sees Sonic and flies to his rescue. The two fly back to Selmondi Prosper, location of Selmondi City, Kelistona Island, and surrounding areas. The tornado lands in Red Granite Zone, and Sonic and Tails run through the zone. Meeting up with Eggman, they both destroy his Egg Boar, a large mechanical swine. After he escapes, the pair hops into the Tornado and follows him to Secret Space Base Zone, which is similar to the Death Egg, but features the robot-making factories and Mega Muck pools of Chemical Plant inside. Sonic and Tails run through and meet up with a damaged Metal Sonic. Defeating him, Eggman breaks through the wall with Eggzilla, a giant mechanical Reptile piloted by Eggman. This is the final boss of Sonic's and Tails' story. After defeating him, they escape as Secret Space Base is exploding. When they land the Tornado near Station Square, they watch as 7 streaks of different colors fly from Angel Island. This is where their stories end.

Tails' story

Sonic and Tails are running after Dr. Eggman, who, as usual, is up to no good. This begins the game with the Vs. Eggman Mach Speed section, where Sonic and Tails must avoid the firing of the blasters attached to the back of Eggman's Eggmobile. At the end, all of a sudden, a portal opens and Sonic can't stop in time. Tails is left to fight against Eggman alone. He destroys Eggman's Eggmobile, but he uses a crystal to escape through a portal. Tails is then left alone as several screams are heard from Emerald Coast. Tails arrives to people running away from the beach as a giant Balkiry flies over. Tails chases the enlarged Badnik through Emerald Coast in a mach speed mission. Tails reaches the end and destroys the large Badnik. From this point on, Tails will explore areas of the area not seen in Sonic Adventure 1 or 2. Tails, in search of Sonic, arrives at a large, destroyed Chao Garden, Chao Ruins. Tails reaches the end and Metal Sonic flies overhead. Tails flies after him and ends up in Eggman's Sky Base near Windy Valley. Tails goes through the base and ends up locked in a room with Metal Sonic. After a battle, a damaged Metal Sonic escapes and flies into space, where he is rescued by Eggman. Tails flies down and runs into Silver, who is searching for Marine. Tails then decides to go on a scouting mission for Sonic, so he hops into the Tornado and flies around. This leads to Sky Chase Act 3 (a callback to Sonic Adventure). Tails then sees Sonic towards the end of the stage, and Tails must be just at the right place at the right time to catch Sonic. After Tails catches Sonic, the two fly to Selmondi Prosper, location of Selmondi City, Kelistona Island, and surrounding areas. The tornado lands in Red Granite Zone, and Sonic and Tails run through the zone. Meeting up with Eggman, they both destroy his Egg Boar, a large mechanical swine. After he escapes, the pair hops into the Tornado and follows him to Secret Space Base Zone, which is similar to the Death Egg, but features the robot-making factories and Mega Muck pools of Chemical Plant inside. Sonic and Tails run through and meet up with Metal Sonic. Defeating him, Eggman breaks through the wall with Eggzilla, a giant mechanical Reptile piloted by Eggman. This is the final boss of Sonic's and Tails' story. After defeating him, they escape as Secret Space Base is exploding. When they land the Tornado near Station Square,they watch as 7 streaks of different colors fly from Angel Island. This is where their stories end.

Shadow's story

G.U.N has discovered that Zavok and the rest of the Zeti returned after the events of Sonic Lost World and are causing more trouble. Team Dark is originally sent on the mission, but are defeated by Zavok in the opening cutscene. While Omega is being repaired and Rogue allowed to go on vacation, Shadow is given the go-ahead to complete the mission with a new recruit, a wolf named Vortex. However, there are differences between the two that cause them to compete to complete the mission first. The two break away and you are left as Shadow. After Shadow defeats several badniks with various weapons found throughout the first stage, Dark Cavern, Shadow runs into Master Zik. After taking Zik down, Shadow moves ahead to Station Square and takes the train to Rose Garden. After finishing Rose Garden, Shadow returns to Station Square when a large vessel carrying a large group of Eggman's robots within it drops it's payload. After Shadow goes through the Station Square stage gunning down all the Badniks, it becomes an Adventure Area. Shadow explores the town and discovers Zor is spying on G.U.N's Station Square base from the sewers, so Shadow enters Sewer Run through a manhole. Shadow gets to the end and defeats Zor, Shadow then gets a transmission from Commander Tower after climbing back to the surface that Zazz is attacking Westopolis. Shadow hops onto his bike and this begins the Afternoon chase stage, where Shadow must gun down badniks in a mach speed-like stage (being hit by a badnik causes Shadow to fall off the bike and instantly lose a life). Shadow and Vortex meet again and decide to go ahead together to fight Zavok. The pair continue on to Deadly Forest, a forest of deadly trees created by The Deadly Six. Zavok is waiting for them, and the two battle against Zavok and defeat him. They return to Station Square to report their success when they witness Angel Island falling.
