The Main Plaza is a room in the Chozo Ruins. It appears in Metroid Prime.

Description[edit | edit source]

As the name implies, it is one of the major rooms in the area. When Samus enters the room, she will be in front of a large ground, with Beetles hiding in the sand. To her left is the passageway to the Ruined Shrine, and on her right is a decomposing Cyrlic tree. In front of her is a Half-pipe that she cannot use until she gains the Boost Ball. The Half-pipe is used to get a Missile Expansion in an alcove. Samus must climb several stairs to get to the next floor of the room. Far above on the right is an indestructible door and Energy Tank, Samus will have to enter the room from the Vault to gain it. She will also find several platforms leading to a damaged bridge (stones had fallen from the walkway). Another Cyrlic tree that has been forcibly intertwined to form a bridge leads to two War Wasp Hives. Above the lowermost floor is a Grapple Point; scanning it states that it is too far away to use. Samus must enter the room from Piston Tunnel to be able to reach it. Later on in the game, the Beetles are replaced with a single Plated Beetle.

A Hidden World can be found in this room: [1]

Items[edit | edit source]

Missile Expansion
In an alcove above the half-pipe in the center of the room, which can be accessed with the Boost Ball. It is also possible in the NTSC GameCube version to get this using a Ghetto Jump on the side of the half-pipe.
Missile Expansion
Beneath a stump in the Cyrlic Tree opposite the entrance to the Ruined Shrine, which can be blown open by a Super Missile.
Missile Expansion
On a ledge above the entrance to the Ruined Shrine, gotten by grappling across the room after going though the Magma Pool and Training Chamber.

The room's Energy Tank.

Energy Tank
On a high ledge. Accessible only through a one way door from the Vault

Scans[edit | edit source]

Cyrlic tree (not named)
"This tree seems to be weakened due to cellular decomposition."
Holobanner
"Passageway to Shrine"
Missile Expansion
"This object rests at the top of a very smooth inclined slope."
Tree leaf
"These leaves appear to be unnaturally dried and withered."
Energy Tank
"The ledge this object rests on cannot be reached from this room."
Door
"This door can only be opened from the other side."
Stones
"These stones appear to have fallen from the walkway above."
Tree bridge
"These large branches have been forcibly intertwined, forming what looks to be a bridge structure."
Etching

Samus uses the Grapple Beam to reach a Missile Expansion.

Trivia[edit | edit source]

  • The Main Plaza was modeled and skinned by Elizabeth Foster.
  • Jack Mathews stated that the Main Plaza was one of the first rooms built during the development of Metroid Prime, and was subsequently used for stress testing as the game was created. The room's performance impact can be seen when Prime is played on an emulator such as Dolphin, as it frequently causes frame rate drops and stuttering.
  • The Birds flying around in the sky can be shot at and killed, their feathers slowly drifting down before disintegrating.
  • The Main Plaza is the room with the most Missile Expansions in the game.
  • By using the Space Jump Boots from the roof over the entrance to the Ruined Shrine onto a ledge seemingly blocked off by sand, one can get the Missile Expansion there early. Strangely, the Grapple Point over the Plaza can be scanned here for its Logbook entry, even if the player has not yet acquired the Grapple Beam.
