Double Boost

Double Boost is a move set to appear in Sonic Forces. It is a collaboration technique between Sonic the Hedgehog and the Avatar where they combine their strength to perform an augmented Boost.

Description
When performing the Double Boost, Sonic the Hedgehog and the Avatar focus their power into their hands and then high-five each other. The two then do a midair Spin Jump before dashing away side by side, each one performing a Boost that augment the other, thus greatly amplifying their combined speed.

The Double Boost is triggered when a Real-Time Interaction is initiated, in which the player must tap / enough times within a few seconds. If performed correctly, Sonic and the Avatar will boost away like when performing the Boost, but at far greater speeds, while a short version of the song "Fist Bump" replaces the background music. The Double Boost ends when the Boost Gauge runs out, but it can be refilled by destroying enemies and collecting Rings.
