Prototype Wiki

Sprint Upgrades are a variation of evolutions to the Prototypes' leg musculature. These upgrades allow them to sprint at high speeds, allowing them to regenerate in a heated battle or outrun their enemies.




Diveroll is an excellent defensive maneuver to avoid projectiles and attacks. It can be used to evade the swipe attacks by hunters and attack the foe after dodging its initial attack.

This ability is a great alternative from either jumping or airdashing away from the enemies. Since the attacks can be avoided, Mercer can stay close to the enemy and counter the attacks easily.
