Ship Grapple Point
A Ship Grapple Point is attached to certain heavy objects in Metroid Prime 3: Corruption in order to lift them. This can be done via the Ship Grapple upgrade. Using your Command Visor, you can point your ship to a Ship Grapple Point, and it will come and launch it's Grapple at it. It will then proceed to lift it and carry it away. This feature is extremely helpful, and you will use it at various times throughout Metroid Prime 3: Corruption.
