Sonic Adventure 3 (ソニックアドベンチャー3 Sonikkuadobenchā san? ) is an upcoming, platforming game developed by Sonic Team, and is to be published by SEGA in 2021. (2022 for the 3DS handheld version) It is the threequel to Sonic Adventure and Sonic Adventure 2.

Sonic Adventure 3 is to be released late 2021 to celebrate Sonic The Hedgehog's 30th anniversary. The game will also come with a special collectors edition for consumers who pre-ordered the game, or buy it when the game comes out. The collectors edition is supposed to have a special figurine, a Sonic medal, the Sonic Adventure 3 soundtrack, and a memorial booklet. This game introduces 15 playable characters, and is one of the few games to feature Dr. Eggman and Metal Sonic as playable characters. This game also dives into the character development of the characters in the game.


Development

Sonic Adventure 3 is being developed by Sonic Team, and published by SEGA. After the release and success of 2017's Sonic Forces, social media coordinator Aaron Webber notified an increas e in requests for a sequel to Sonic Adventure 2. In the summer of 2018, Aaron posted a poll onto the Sonic The Hedgehog's twitter page, asking if the fans would want Sonic Adventure 3 as the game to celebrate Sonic's 30th anniversary. With a bunch of positive votes going on the side of bringing the game to light, the game began development sometime in late 2018, and the following year's E3 announced the game.

The game is meant to be more expansive than the last two games have been. Sonic Adventure 3 is to have 14 playable characters each with their own stories and different playstyles.

A Chao Garden is also confirmed for release.




Gameplay

Single Player

Sonic Adventure 3 takes hints of the gameplay styles from it's prequels, and Sonic The Hedgehog 2006. The player can choose one of the 14 selectable characters, and has the option of progressing through them at any time. (When unlocked) There are also 3 different alignments that is centered around the theme  of the character's story. The "Heaven" side consists of the storylines for Sonic, Tails, Knuckles, Amy, and Blaze, the "Neutral" side has Shadow, Rouge, Silver, Espio, and Mighty. While the "Dark" side features Dr. Eggman, Metal Sonic, E-123 Omega, Fang, and Shade the Echidna. Sonic's story is unlocked when the game starts, and other characters are unlocked  when a character that the player is controlling encounters said character, meaning the order in where characters are unlocked depends on how the player encounters them. (For example, Sonic meets Knuckles later on in the story, which would make Knuckles the 4th unlockable character, however, Tails encounters Knuckles first, which would make Knuckles the 3rd unlocked character.

Each character has a different play style, with some being more similar to others. All characters have separate storylines, not connected via their alignment, and all stages are shared between the different characters. (With some being exclusive to a select few.) When all character's stories within a alignment is finished, then that alignment's story will appear, consisting of the characters of said alignment working together. This all is wrapped up in a final, concluding story, named the Annihilation Story.

The flow of the game is seperted in sections: The hub zones, and the action zones, similar to Sonic Adventure.

Hub Zones

Hub Zones are basically hub worlds. They areas where the player can do various things, such as shop, go to an Action Zone, talk to various NPCs, or take place in missions.

There are 7 different Action Zones (Excluding the Action Zone in the Annihilation Story)

  • Splash Resort - The main setting of the game and where the story revolves around. This place is like a hotel resort, much like the hotel area of Station Square.
  • Splash Central - The city area of Splash Resort. This is where the character can shop and buy items or upgrades. This is where the G.U.N. headquarters is located. This is also the largest Hub Zone.

  • Splash Park - A festival that is running through the month if where the story takes place.
  • Eggman Land V2.0 - Eggman's newest carnival. Most character's stories conclude at this location.

Action Zones

These are stages that you play to progress through the story. These stages are shared between all of the characters, and are often altered to suit the character's playstyle, or they put the character in a different section of the level.

There are 30 Action stages, (Excluding the Action Zones in the Annihilation Story)  * Paradise Rush - The coast of Splash Resort. This is the starting stage for Sonic, Amy, and Metal Sonic.

The game plays like a usual Sonic game. The player controls one of the 15 characters and has to use their abilities to achieve the objective the stage calls for. The objective differs between the character and the stage, but it normally consists of getting from point A to point B, or collecting a set amount of objects. This game, is more based around ranking and score than it's proceeding g

ames. Each character has a set of skills they can use to achieve their goal.

This game's ranking system goes from F to S, with the ranks in between being E, D, C, B, and A, and there is plenty of ways to get a high rank. The game also has the return of the Chaos Drives, and the Chao garden, as well as upgrade for each character, and th

e mission system which is changed.

Mission System

Similar to Sonic Adventure 2, this game has a Mission system, however, it's more like a checklist than separate missions. The usual 6 missions go like this

  1. Get an S rank in the stage
  2. Get a set amount of rings and reach the goal.
  3. Find the lost chao.
  4. Complete the stage with a certain score
  5. Complete the hard version of the stage.
  6. The last mission depends on the stage the character is in.

Characters

As stated, there are 15 playable characters each with their own playstyles. Although, some playstyles are similar to others, they normally have many changes to differ from the other characters. Like Sonic Adventure 2, all characters have a rival or counterpart, however, this isn't related to their alignment, as characters can have a rival that is in the same alignment as them. (Example: Blaze and Amy)

Team Hero

Sonic The Hedgehog 

Adv3Sonic.png

The fastest thing alive and the main character of the story. His story revolves around  Eggman the most, and is also centered around his family and origin. His gameplay is the most basic out of the cast, with him having his gameplay from Sonic Adventure 2, with most of his moves being intact. He can still homing attack, and spin dash, while learning moves like the Lightspeed Dash. (which is changed dramatically) He's the first unlocked character when the game starts. His rival is Shadow The Hedgehog.



Miles "Tails" Prower

A young fox cub with 2 tails, who is Sonic's best friend. His story revolves around him trying to make a name for

Tails by mintenndo-d7ap20h.png

himself and overcoming his own fears. His gameplay is different from his others before, and is more of a "get to the goal" based playstyle, except his levels are centered around his flight ability and the gadgets he uses. Tails' stages are more open than Sonic's. He is unlocked by encountering him with another character in their respective storyline. (Tails would be the first character you unlock due to Sonic meeting him first.) His rival is Dr. Eggman.



Knuckles The Echidna

Knuckles is the guardian of the master emerald, and used to be the last of his clan before Shade appeared. His

story revolves around him recieveing the now broken Master Emerald, and learning more about his past. Knuckles keeps his usual treasure hunting gameplay, with him having to find 5 objects per level, rather than 3. However, his radar acts like a mixture of SA1's and SA2's system. Knuckles' radar will target the leftmost emerald piece, and the hints will revolve around that said piece, however, if another emerald piece is nearby, the radar will activate. He also has a more in depth fighting system, similar to the Werehog stages in Sonic Unleashed. His levels are also more spread out. His rival is Shade The Echidna.



Amy Rose

Amy is a teenage hedgehog who has a big crush on Sonic. Her story revolves around this crush on the blue hero,

She plays in a style similar to Sonic's, but her gameplay is more suited for beginners. As such, her levels are more streamlined, and focus more on platforming. She can use her piko piko hammer for many things, and can turn invisible to avoid certain enemies. She also has Cream following behind her, similar to how Tails does with Sonic. Her rival is Blaze The Cat.



Blaze The Cat

A princess from the Sol Dimension, In this game, she is shown to have a slight crush on Sonic, however, this 

2016 legacy blaze render by nibroc rock-daooomb.png

doesn't evolve much. Her story is a search mission for the Sol Emeralds, which got lost and thrown into the fetch and chase game that the Chaos Emeralds got into. Her gameplay is similar to Sonic's, but has a Sonic Rush influence with it. Blaze's stages revolve around adreniline, and acrobatics rather than pure speed. She also has the highest main jump in the game. Her rival is Amy Rose.




Team Neutral

Mighty The Armadillo

After being missing for a long time, Mighty returns with a brand new gameplay style! His story revolves finding the

Chaotix, who've been missing for a while and stopping Eggman's latest scheme. His gameplay differs from most characters, as Mighty has to find keys in stages, which progress him through the stages. In turn, his stages are a mixture of being open and linear, due to there being a wide range of keys for him to collect and use. His rival is Fang The Sniper.




Shadow The Hedgehog

An artifical life form created by Eggman's grandfather. Along with Rouge, he is investigating the influtration of the 

Shadowgenerations.png

GUN base caused by Eggman, while confronting the Shadow Androids.

Her rival is Silver The Hedgehog.

past, but after getting kidnapped, Eggman rewired him to be a killing machine.
