Lara's Treasure Vault (TR2)
Lara's treasure vault is a room in Tomb Raider II found in the main hall of Croft Manor. The room seems to serve more as a basement than treasure vault, seeing as it's rather dark and empty, and only houses a few items, such as a rolled-up carpet and a shelf.
In order to access this room, Lara will need to head to the middle of the hedge maze (outside the manor) and press the button which opens the door. The door is timed, so Lara must rush out of the maze and back inside the manor before the timer expires.
