Triple Boost

Triple Boost is the final move used to defeat the Death Egg Robot in Sonic Forces. It is performed by Modern Sonic, Classic Sonic, and the Custom Hero.

Description
When performing the Triple Boost, Modern Sonic, Classic Sonic, and the Avatar spin together in a clockwise motion while boosting forward simultaneously. The player is then prompted to repeatedly press X/Y in the time allotted to generate the power needed to destroy the Phantom Ruby forever and put an end to the Eggman Empire.
