Hall of Eyes is a room in Temple Grounds from Metroid Prime 2: Echoes. It takes its name from the corridor connecting from Meeting Grounds, which contains many red eye-like decorations on the walls. The room has three levels (one which is merely a stepping stone to the highest level). In the room is a Portal which can transport the user to Dark Aether. Samus must use this portal to reach the next room when she first enters it (because of a Green Hatch, which she cannot destroy due to lack of Super Missiles). The Dark Aetherian version of this room was Base Access.
