Gauge Up

The Gauge Up is an Power Up item that appeared in Sonic The Hedgehog (2006).

Description
The only purpose of the Gauge up item is to replenish the Action Gauge. It has no effect when picked up by Sonic as the Custom Actions did not depend on the Action Gauge, but can be useful for Shadow to use his Chaos Boost powers and for Silver to extend his  levitate  in the air or to refill The action Gauge faster.
