Sonic Adventure 3 is a 2015 video game, based on the first two games of the same title. It is a direct sequel to Sonic Heroes/Shadow the Hedgehog, and resumes the classic gameplay style of the "Adventure Series". In this game, you assume the roles of 3 default characters, and includes 9 other characters to be unlocked! Following the events of Heroes/Shadow the Hedgehog, Sonic has finally come to a peace of mind, and wants to relax. Unluckily, no hedgehog gets to rest as long as Dr. Eggman is around. Sonic does nothing to disturb the old coot, but Eggman doesn't seem to care. Will Sonic beat Eggman this time? Will Eggman be victorious? Are you going to really answer any of these questions? Find out below...


In the Main Menu, you will find these gameplay modes: "Story", "Trial", "Challenge", and "Chao Garden". "Story" mode brings you to a character selection screen, where 3 different characters are defaultily available; Sonic the Hedgehog, Tails the Fox, and Knuckles the Echidna. As you progress through "Story", you unlock MORE Story's. You may find the secret characters in the "Characters" Section Below. Gameplay is extremely simular to the first "Sonic Adventure", whereas your character must complete an objective/beat a time limit. This game also celebrates the return of..."Adventure Fields!" There are 4 different Adventure Fields in the game; Coconut Grove, Blue Castle, Cold Shelter, and Green Hill! Each Character will explore each Adventure Field as they continue each task. Green Hill from previous Sonic Games makes yet ANOTHER appearance!

"Trial" is sort of like a replay mode. You may replay any mission you have already completed, and win those Emblems! Get all of the emblems in Trial!

"Challenge" is simular to sonic Generation's "Challenge Acts". You must complete a special objective within that level, wether it be Collecting chao, Collecting rings, Destroying enemies, or escorting a Rabbit through a mechanical gear theme!

"Chao Garden" is self explanitory. You may enter the Chao Garden at any time, with any chracter. Each Character starts off with 2 default eggs, and they will hatch on their own within 3 game hours (30 minutes in real life). Remember, every character gets their own garden.

Sonic's Story

After bringing down Metal Madness in Sonic Heroes, Sonic and his two companions take part to Coconut Grove, where they decide to vacation. However, Tails' Chao device gets a disturbance over on the other side of the Island. Sonic, Tails, and the Red-Headed Echidna go over to investigate, when they catch Shadow trying to steal a Hero Chao. Sonic goes after him, racing him through the island. (Level: Coconut Grove).

After Sonic catches up to Shadow, he explains that he must collect enough Chao for a plan he is working on. When he is questioned by Sonic, Shadow presses a button on a ring he is wearing, and "POOF". Shadow was gone. Sonic is shocked. Sonic heads back to the duo and exclaims he wants to find out what's going on. Tails exclaims that there is an old folks tale, about a "Medium" who lives at a place called "Blue Castle". Sonic realizes he can use the Medium to find out what's going on.

Sonic and friends arrive at Blue Castle to see that the drawbridge is already down. Sonic and Tails go to investigate, while Knuckles continues to adore the castle. Sonic and Tails enter, where there is no one in sight. Suddenly, the room begins to shake, and the drawbridge suddenly raises upward, leaving Knuckles seperated. Sonic and Tails run through the castle, in search of a medium...or an escape. (Level: Blue Castle).

Sonic and Tails eventually arrive at a giant room, where a medium named "Keesha the Jaguar" offers Sonic a reading. After reading his palms, Keesha tells Sonic that he will face a certain death in the future, at the hands of an "Egg." She also says that a black force will exterminate your love. Sonic and Tails quickly exit, while Knuckles asks how it went. Sonic fears that he is going to die soon, and must stop Eggman before that day.

Sonic knows that the only problem is...he doesn't know where Eggman IS! Suddenly,a 15 mile wide ship comes into view, with many lights visible above. Tails' faints as Knuckles falls to his knees. Sonic is just plain shocked. Eggman's voice then calls: "OHOHOHOHHOHO. Think you can beat me now Sonic!? Let's see you FOIL THIS!". Sonic accepts the challenge, and makes his way to the top of Coconut Grove. (Level: Forest Rush).

After landing on the edge of the ship, sonic enters, to find that the entire place is a labrynth. Sonic races through the halls, and eventually runs into old Dr. Eggman. (Level: Labrynth Lust). Sonic confronts Eggman, only to be captured in a glass cell. Sonic is forced to look outside the giant window, seeing Tails and Knuckles down Below. Eggman explains that he is going to destroy the world with his new weapon! A nuke, which will set a fire throughout 20 miles of the blast radius! He then then fires the weapon on his ship...BOOM. The middle of the forest is set on fire! Sonic watches as Tails and Knuckles flee, as the fire begins to spread throughout the island. Sonic's anger forces him to break out of his cell, and run for his life! (Level: Eternal Escape.)

Sonic emerges from the sip, only to land in the ocean, and watch as Coconut Grove is completely set on fire. Sonic has no idea where Tails and Knuckles are, and swims to Blue Castle, left no other choice. After nearly losing hope, Sonic remembers Eggman's last techonology on the Egg Carrier! Sonic rushes to Mystic Ruins, where he sees the Egg Carrier is completely underwater. Bracing Himself, Sonic runs underwater, and quickly into the Egg Carrier, where there is still much air to breathe...(Level: Cold Shelter).

Sonic aquires a bunch of Eggman's robot and techonology peices, and suits up in...The Egg Robo! Sonic gears up in his new suit, ready to crush Eggman! "OHOHOHO". Sonic hears. He turns to see Eggman, in a simular suit. "Bring it on!" Sonic and Eggman both exclaim. (Level: Eggman Bash). Sonic nearly wins the fight, but Eggman throws an uppercut, throwing sonic to his feet. Eggman bursts through the top of the Carrier, flooding the entire ship! Sonic is forced to abandon the Egg Robo, and escape the Cold Shelterless Egg Carrier! (Level: Flooded Shelter).

After escaping the death trap, Sonic abandons his plan to save the world, and retreats to his home...Green Hill. Heartbroken, Sonic lays in the grass as he hears a familiar voice. "Sonic!" Amy and Cream cry out. Amy helps Sonic regain his cofidence by telling him he's taken down a Death Egg...twice, beat an Egg Carrier, defeated the ARK Colony, and killed Metal Sonic. Together, the 3 devise a plan to take down Eggman! (Level: Green Hill: The Remake).

Meanwhile, Eggman, Shadow, and Omega dump the last few Hero chao's into Eggman's power generator, and laughs in success. Here it is revealed that the Hero Chao's energy is the source of the nuke! NOTHING CAN STOP HIM! That's where he's...almost wrong. Sonic, Amy, and Cream emerge into the main room, ready to beat the HELL out of Eggman. Sonic is surprized to see Team Dark on his side, as the two sides begin the battle...(Level: Independence Day). Sonic wins against Shadow, and Cream loses against Omega. Omega then flees with Cream as Eggman gets another tiny weapon out. Eggman shoots the beam at Sonic, hitting him square in the chest. Sonic then hits the giant window, shattering it and flying out of the back. "Sonic!" Amy yells. Omega then captures Amy, rendering her useless. Cream and Amy shout for help as Sonic lays on the burnt island of Coconut Grove...

Tails' Story

Tails travels with Sonic and Knuckles to coconut grove, where they decide to relax and wind down. However, his chao device goes crazy, detecting activity on the other side of the island. Tails goes over with Sonic and the red guy to check out the scene. Sonic soon goes after Shadow the Hedgehog, who has just stolen a Hero Chao. Tails then notices something in the trees.

With the help of Silver, they fly up to the ship, and break in, rushing through the halls (Labrynth Lust).

After finishing off Shadow and Eggman, Tails and Blaze corner Eggman, demanding answers. Eggman then laughs, and blasts the 3 to their feet. Eggman picks up Shadow, fleeing the room. The room is then sealed, with the doors closing and locking. The flaps on the ship then plug up the window, as a pipe is popped out of the wall. "Guys?" Tails anxiously asks. Suddenly, rushing water comes through, flooding the entire room. Tails then realizes there is no escape, and the room is quickly filling with water. All 3 look at each other, scared. The water is at chest level before they realize what their fate would turn out to be...

He is then shocked by Tails and Sonic, rushing up to him. Tails then informs Sonic of the "medium" at Blue Castle, giving Knuckles Shivers. The 3 then go to Blue Castle, while he stays at the entrance, trying to determinate the cause of the flash. The drawbridge then goes up, seperating him from Sonic and Tails.

Reaching the drive, Eggman arrives once more, who tells Rouge that Sonic has given up, and is at Green Hill! Rouge is teliported there, where she is told to transform into a clone of Amy. Rouge ALSO creates a clone of Cream! However, Shadow appears, and tells her to get lost.
