Adrenaline is a power-up in the Blast Ball mode of Metroid Prime: Federation Force, and the standalone demo Metroid Prime: Blast Ball. It is obtained randomly by repeatedly shooting the ball and collecting the item when it spawns. When acquired, it temporarily supercharges the Mech of the contestant who collected it, enhancing their speed and strength. There is a noticeable "coil" sound when Adrenaline is active. It is represented by a yellow lightning bolt not unlike that of the Screw Attack symbol.
"Mech movement speed, weapon energy recovery, and weapon projectile speed are all increased when this item is used."
