Proving Grounds Lift is a room in Pirate Research on the Pirate Homeworld in Metroid Prime 3: Corruption. It is where Samus Aran is pointed to when she receives a transmission from Gandrayda impersonating a Federation Marine. When Samus first enters the room she will see Gandrayda being attacked by two Pirate Militia. When Samus defeats them, the Marine will instruct Samus on how to activate the Elevator in this room and also tell her about the Hazard Shield. To activate the elevator, a panel with two security levers must be activated at the same time.
