Speed Boost

Speed Boost is a technique mainly used in Sonic Rivals and its sequel Sonic Rivals 2.

Overview
While encountering a boost object or held by a hoop, the Speed Boost is executed by pressing the button. The button must be pressed quickly otherwise the opportunity is lost and the character simply vaults over the boost object or dropped from the boost object. The Speed Boost will launch the character horizontally, mainly for accessing zipping past gaps that lead into a shortcut or a needed power-up.
