Dissidia: Sonic Alliance is a fighting/role-playing fanmade game, being the next installement of Dissidia franchise; it will be created by Sega, with cooperation from Square-Enix (the creator of the original Dissidia game; Dissidia: Final Fantasy), and published by Fantendo for PlayStation Portable.

The game is set to be released on 23 June 2011, as one of the games to celebrate Sonic's 20th anniversary.


Dissidia's genre has been described as "dramatic progressive action," featuring characters battling in a 3D environment with the ability to level up and customize characters. The game unites thirty characters from various installements of Sonic the Hedgehog series, some of them being characters from fan games or anime Sonic X. Characters from Dissidia: Final Fantasy, Chaos and Cosmos, appear as god of discord and goddess of harmony, respectively. As well as every character in the game. Each of these gods has summoned twelve warriors to fight for them against the opposing god. Now, Chaos and the villains have shattered the Chaos Emeralds into tiny pieces and wounded Cosmos, and it's up to the heroes to recover the Emerald Shards and restore the Chaos Emeralds, and, in turn, balance to the universe.


In storyline gameplay, players move about a token representing their character on a tiled gameboard, and move up to objects and enemies and interact with them using "Destiny Points". Every time the player moves their character, they must use one Destiny Point, and can sometimes earn more by defeating enemies. If the player is able to finish a stage without using all their Destiny Points, they earn a special bonus. When the player reaches the Stigma of Chaos at the end of the stage, the stage is completed and the player is awarded Rings and Player Points (PP) depending on their remaining Destiny Points, HP, and other factors. Sometimes at the end of a stage, the player fights another character. Dissidia is an action-based fighting game mixed with RPG elements. Battles take place on fully rendered 3D fields, with characters free to roam around as they please. The environment can also be interacted with, with characters able to run up walls, grind along railings and destroy pillars and floors with attacks. In battle, players have two types of attacks - Bravery and HP. Every character has their Bravery Points located above their HP bar, and whenever they land an HP attack, the damage done is equal to their Bravery. Striking an opponent with a Bravery attack will drain their Bravery and increase the attacker's, thus increasing the HP damage they can do. If a player's Bravery is reduced to below zero, they enter "break" mode, where they cannot inflict HP damage, Bravery attacks against them do increased damage, and their opponent receives a significant boost to their Bravery. Every character has their own unique fighting style and attacks, usually based on the character's abilities in their original game. In addition to Bravery and HP attacks, players can use Summons from Final Fantasy games to assist them in battle, and can find new Summons in certain stages or as part of a stage bonus. There is also an "X Bar" meter which fills up during battle by collecting the X Force that appears when players strike each other, or the randomly appearing X Cores. Once filled, the character can enter X Mode which grants a character-specific bonus and gives access to an Final Attack, a special move that deals massive damage to their opponent. These moves are often a reference to each character's signature attacks in games, such as Sonic ramming onto enemy several times in super form or Nightmare using Bloody Piercing. After the battle is over, characters are rewarded with Rings, EXP, and Abilty Points (AP). Further awards may be given if the player fulfills certain conditions during the fight itself, such as winning within a time limit or landing an attack of a certain strength.


The story follows the conflict between Chaos and Cosmos and their allies, drawn from Sonic games. Backstory for the various characters are also given in "Reports", which are divided into Cosmos Reports and Chaos Reports. Within the history of Dissidia, Chaos and Cosmos have been at war with each other for an eternity, but thus far neither side has emerged victorious. As the game begins, it seems Chaos has finally gained the upper hand. The Heroes of Light, led by Sonic, find Cosmos mortally wounded from a battle with Chaos. With the forces of light in peril, Cosmos entrusts the heroes with the task of recovering the shards of Chaos Emeralds and restoring them. This, in turn, can save their world.

Though they do not fully understand the quest Cosmos sets before them, the heroes set out to retrieve the Chaos Emeralds in the hopes they can end the war. Each of the twelve heroes has a storyline following their journey to recover the shards of Chaos Emeralds. Each storyline also parallels to a certain extent the events, or at least the spirit, of the storyline in previous Sonic games - Amy's story deals with her love for Sonic and and fierce rivarly with Rouge the Bat, Mimi's concerns her tragic past and the magical power within her, Knuckles is torn between helping his friends and fulfilling his duty, and so forth.

As the game progresses, the heroes confront both the "Manikins", Chaos' troops that resemble both heroes and villains from the game, as well as real villains, such as Dr. Eggman or Vision. Finally, after the 7 Chaos Emeralds are restored, the heroes return to Cosmos, but Chaos appears and incinerates the goddess, and departs back to his realm. With Cosmos gone, her power over the heroes fades and they begin to fade away. However, with the last of her strength inside them, the Chaos Emeralds are able to keep the heroes from fading. Determined to avenge Cosmos and see her will fulfilled, the heroes journey to the Chaos Shrine, confronting villains once again. At this time it is revealed that the villains allowed the heroes to collect the Chaos Emeralds, which contained Cosmos' light, and their shining caused Cosmos to weaken to the point she could not be revived, a "perfect death". Now that Cosmos is gone for good, the cycle of war is over, with Chaos as the ultimate victor. Resolving to destroy Chaos and claim vengeance for Cosmos, the heroes defeat the villains once again in battle.

At the Chaos Shrine, the seven Chaos Emeralds combine to open the path to Chaos' realm, and the twelve heroes confront the god of discord on his throne. After an epic battle, Chaos is defeated and is consumed in flames as the heroes vanish. They appear in the fields outside Green Hill Zone, and after some reminiscing, they part ways, saying they will meet again. Sonic begins dashing toward the horizon.

In the secret ending of the game, unlocked after obtaining all the Reports, Cosmos is shown to be alive in her world. She has a discussion with Spirit, implying that the war still has not yet ended.

Gameplay Features


A total of thirty arenas appear, 28 serving as an important site of conflict between the heroes and the villains in Sonic games, and the other two hailing from Dissidia: Final Fantasy. Each arena can be played as a basic arena with no special features, or as a stage with a special "gimmick", effectively doubling the number of arenas to sixty. For example, the Station Square stage's alternate form is sometimes attacked by Perfect Chaos.

Both summoned the characters from the series with their own motives: Cosmos wishes to protect the Chaos Emeralds from the forces of Chaos and keep order, while Chaos wants to take control of the Emeralds and upset the balance of power between good and evil. The narrator of the events occurring in Dissidia is Spirit, one of the elemental gods, representing the wind.

There are twelve characters of heroes, playable at start of the game and in their respective "Destiny Oddyseys", plus three secret hero characters and villains.
