The game's other major addition is the inclusion of a suite of Force powers for Luke. They are learned by collecting hidden orbs on the Dagobah level, and add a second special bar that depletes with each usage of a Force power. Power-ups include health items, weapon upgrades, screen-clearing detonators, and orbs that restore Luke's Force power. Passwords have also been added, and are given upon completion of each of the game's 25 stages.
