Earthshaker

The Earthshaker is one of the skill moves usable to Sonic the Werehog that appears in the PS2/Wii version of Sonic Unleashed. It is unlocked at the Orb Result screen after the player has collected 36000 Dark Gaia Force Orbs. When using this move, Sonic performs a gigantic beating via moving his arms back and forth. It is the strongest move for Sonic the Werehog in Sonic Unleashed.

Description
When performing this move, Sonic, after making four hits in a combo, will stop fighting, and will then slam both of his arms down numerous times on the ground, similar to the Beatdown move, only the foe(s), namely the minions made by Dark Gaia, will receive more damage than any other move Sonic can use.

To perform the Earthshaker in gameplay, the player must first hit an opponent(s) at least four times (the Earthshaker move can work even if the player goes beyond four combo hits). Then, if pressing the A Button on the Nintendo Wii version or the button on the PlayStation 2 version, the player will activate the Earthshaker move.

Trivia

 * The player can not activate this move while in Unleashed Mode, as while triggering the controls for the Earthshaker while in Unleashed Mode, the player will instead activate the Unleashed Tornado.
