Access ramp

Access ramps are retractable ramps present on the two Olympus-class battleships seen during Metroid Prime 3: Corruption. Why they are retractable is unknown, although it could be for maintenance or security purposes.

Shortly after landing on the G.F.S. Olympus, Samus finds two retracted ramps in Docking Bay Access. The control switches for both ramps have malfunctioned, preventing their use. To continue on to the Ready Room, Samus must use her Charge Beam to shoot the control switches and loosen the jammed parts, allowing the ramps to function again.

The Stairwell on the G.F.S. Valhalla, which has a similar layout as the Docking Bay Access, also contains access ramps, which are once again unusable on the first visit. One of them has been destroyed, while the other lacks power. Samus can restore power by inserting two Energy Cells into their respective Stations. This action causes the functional ramp to slide and lock back into place.
