Security lever

A manual override is an interactive mechanism used several times in Metroid Prime 3: Corruption, most often to power up a system or unlock an area. It is represented as a thruster handle that Samus must pull out, turn counter-clockwise and push back in. This is accomplished by making the respective motions using the Wii Remote. The feat was demonstrated in several commercials for the game.

The mechanism first appears on the G.F.S. Olympus, where it opens the Security Station for Samus to undergo a biohazard scan, and then another one inside the box opens its exit. Ghor, who goes through the security check before Samus, interfaces with the machinery instead of using the manual override.

Arriving on Norion, Samus finds that the three Fedtech Plasma Generators powering the planet's Defense Cannon have been knocked offline by a Space Pirate attack. It becomes her objective to restore power to these generators so that the Galactic Federation can respond to the threat. To restore power, Samus goes to Generator A and C (Rundas reactivates Generator B for her). In Docking Hub Alpha, a manual override must be activated to call an elevator for Samus to use to progress further into the base. In Generator A, the override is blocked initially by several "Jolly Roger" Drones and some debris, and powers up a Hand Scanner that activates the Generator when Samus uses it. In Generator C, the override is unobstructed, but Samus must navigate a series of Morph Ball tunnels and fight Meta Ridley in the shaft under Generator C to dislodge the stuck Generator before she can use the Hand Scanner.

A manual override is also used to power up the Satellite Uplink Unit in the downed G.F.S. Theseus, disable a force field blocking progression in the Overgrown Ruins of the Bryyo Thorn Jungle. Finally, in the Proving Grounds Lift on the Pirate Homeworld, two manual overrides appear on an elevator activation console. A "Captured GF Trooper" instructs Samus that both overrides must be activated simultaneously.
