Sonic Unleashed is a mobile phone game based on the console video game of the same name.

The game was announced at E3 2009 and was later released on June of the same year in Europe, Middle East, Australia and New Zealand.[1] The game received mixed to positive reviews.


Spoiler warning: Plot, ending details or any kind of information follow.

The story begins with Sonic the Hedgehog attacking Doctor Eggman's spaceship. He falls from the ship and becomes Sonic the Werehog when Eggman steals the Chaos Emeralds from him. Sonic eventually lands in Chun-nan, where he meets a mysterious creature who he gives the name Chip, and the two travel to a town in search of someone who might know Chip's identity.

After fighting Sonic in Chun-Nan and dropping the blue Emerald, Eggman flees to Athens, Greece, and Sonic travels through Apotos to reach him. After another fight in Apotos, Sonic acquires the red Chaos Emerald. He later catches Eggman in the plaza of the city and defeats the Egg Fish, which drops the green Chaos Emerald.

Having been defeated in Greece, Eggman flees to "other parts of Europe." Sonic subsequently chases Eggman to Spagonia, whose boss drops the white Chaos Emerald.

Eggman's Badniks soon after take over the city of Mazuri, in the "Middle East", where Sonic acquires the purple Chaos Emerald. However, using the "power of Gaia", Eggman unleashes his "most powerful robot" on Mazuri. Regardless, Sonic defeats this robot and gains the yellow and orange Chaos Emeralds, thus foiling Eggman's plans for good.


Unlike its 3D counterpart, the mobile version of Sonic Unleashed is a side-scrolling platformer, with elements like loops and underwater sections that the player can enter (without falling into a bottomless pit) and traverse, although the playable characters will eventually drown if they stay underwater for too long. Abilities like the Boost and the grinding maneuver return from the console version of the game.

The game is split into daytime levels played as Sonic the Hedgehog, and nighttime levels played as Sonic the Werehog. Save for Apotos, whose first level changes from day to night half way through, each region's first and third levels are daytime levels while the second level is a nighttime level.

Badniks serves the enemies in both the daytime and nighttime levels. Each nighttime level ends with a boss battle with Eggman in the Egg Mobile, while Apotos and Mazuri's third levels are daytime fights with mech bosses.

In addition to the game's story mode, there is also a Time Attack mode where the goal is to try and break the best record.
