List of rooms in Metroid Prime/Tallon Overworld

Landing Site

The Landing Site on Tallon IV is a room in the Tallon Overworld. It appears in Metroid Prime. This is the first place visited on Tallon IV, where Samus Aran's Gunship lands and remains for the duration of the game. It is raining here, and the room is open to the sky and contains a small waterfall and pond to the southeast. Ledges around the waterfall allow access to the Temple Hall door. There are higher platforms behind the gunship that cannot be reached from this room in normal play before the Space Jump Boots are collected. The Waterfall Cavern can be reached through a short dry slope, partially hidden by rock, near the pool.

Canyon Cavern

The Canyon Cavern is a room in the Tallon Overworld. It appears in Metroid Prime. The cavern is a small cave accessible from the Landing Site, containing foliage around the edges and a patch of sand in the middle, from which a variable number of Beetles erupt on approaching it.

Tallon Canyon

The Tallon Canyon is a room in the Tallon Overworld. It appears in Metroid Prime. This is a large room containing several waterfalls, a pool with Blastcaps, two Great Trees and a number of ledges around it to climb up, and a Half-pipe. The half-pipe can be used with the Boost Ball to reach the high up natural bridge in the room.

Transport Tunnel A

Transport Tunnel A is a room in the Tallon Overworld. It appears in Metroid Prime This tunnel connects the Tallon Canyon to a room with the elevator to the Chozo Ruins. It is short and arched, and contains two Zoomers that crawl around the walls and floor, and a number of Sap Sacs. Several branches that have broken through stone into the room.

Transport to Chozo Ruins West

Transport to Chozo Ruins West is a room in the Tallon Overworld. It appears in Metroid Prime. This is the first of many elevators, entered shortly after landing on Tallon IV. The room is round and contains nothing more than the elevator in the center, which must first be activated by scanning an Interface Module before it can be used. The elevator leads upward to the (south)west portion of Chozo Ruins.

Root Tunnel

The Root Tunnel is a room in the Tallon Overworld. It appears in Metroid Prime. It is a cavern containing a pool of water, with Tangle Weed on the land near the doors. Sap Sacs are present around the ceiling.

Root Cave

The Root Cave is a room in the Tallon Overworld. It appears in Metroid Prime. The cave is a large, roughly cylindrical room that focuses on vertical movement. The very bottom of the cavern has a steaming mound of earth that seems to resemble a large anthill. If Samus comes within close proximity of this mound, six Beetles will emerge.

Arbor Chamber

The Arbor Chamber is a room in the Tallon Overworld. It appears in Metroid Prime. It is a roughly circular room that is open to the sky, with a large tree stump in the middle. Under normal circumstances, it cannot be visited until near the end of the game, after Samus obtains the X-Ray Visor and Plasma Beam. However, it is possible to access early through careful jumps in the preceding room, the Root Cave.

Hundreds of tiny orange-red mushrooms litter the floor; walking in them or shooting them will cause them to release spores into the air.

Transport Tunnel B

Transport Tunnel B is a room in the Tallon Overworld. It appears in Metroid Prime. It is a rock cavern with a number of Zoomers moving around its walls and floor. A bridge allows passage over a shallow pit in the center, in which there is white smoke (most likely from the heat of the nearby Magmoor Caverns), and an alcove in the ceiling contains some Sap Sacs.

Transport to Magmoor Caverns East

Transport to Magmoor Caverns East is a room in the Tallon Overworld. It appears in Metroid Prime. It is a typical elevator room, not much larger than the elevator itself, and fairly tall and round. There is green plantlife and 11 Red Starburst plants on the rocks around the walls, especially higher up. As with all elevators, an Interface Module next to it must be scanned before it can be used.

Gully

The Gully is a room in the Tallon Overworld. It appears in Metroid Prime. Samus travels through the room after using a "half-pipe structure" in the Tallon Canyon. It is a narrow room open at the top, with many Tallon ferns and other plants on the floor. A Glowing spidervine exists near the "ceiling". The rock walls are covered with lichen, green moss and other luminescent objects.

Alcove

The Alcove is a room in the Tallon Overworld. It appears in Metroid Prime. Samus travels through the room after using a "half-pipe structure" in the Tallon Canyon. It is a narrow room open at the top, with many Tallon ferns and other plants on the floor. A Glowing spidervine exists near the "ceiling". The rock walls are covered with lichen, green moss and other luminescent objects.

Waterfall Cavern

The Waterfall Cavern is a room in the Tallon Overworld. It appears in Metroid Prime. Samus travels through the room after using a "half-pipe structure" in the Tallon Canyon. It is a narrow room open at the top, with many Tallon ferns and other plants on the floor. A Glowing spidervine exists near the "ceiling". The rock walls are covered with lichen, green moss and other luminescent objects.

Temple Hall

The Temple Hall is a room in the Tallon Overworld. It appears in Metroid Prime. It is a simple, straight corridor of green stone, obviously not natural; presumably it is of Chozo construction. There is a trio of Seedlings on the ceiling, and two patches of Tangle Weed on the floor.

Temple Security Station

The Temple Security Station is a room in the Tallon Overworld. It appears in Metroid Prime. It consists of a transparent, hexagonal corridor suspended above the Impact Crater, connecting the Chozo Artifact Temple to the rest of Tallon Overworld. Through the energy-shield walls, one can see the Impact Crater itself. As there is an article of Pirate Data in the center of this room, it is assumed to be of at least partial Space Pirate construction.

Temple Lobby

The Temple Lobby is a room in the Tallon Overworld. It appears in Metroid Prime. It is a short, narrow, straight and arched corridor of moss-covered stone, presumably of Chozo construction. Various pillars line the walls on each side, parallel to each other.

Artifact Temple

The Artifact Temple, also referred to as the Cradle in Chozo Lore, is a room and important location in the Tallon Overworld region of Tallon IV. It appears in Metroid Prime. Created by the Chozo who colonized the planet 50 years prior to Samus Aran’s arrival, it was created to contain the spread of Phazon on Tallon IV, with a cipher sealed by 12 Chozo Artifacts. The Temple was later unlocked by Samus to confront the Metroid Prime, the source of Phazon on the planet.

Frigate Crash Site

The Frigate Crash Site is a room in the Tallon Overworld. It appears in Metroid Prime. Obviously, the Frigate Crash Site is where the Frigate Orpheon crashed. The room consists of the exterior of the crashed ship, next to a large pond. Opposite the frigate is a door leading to the Waterfall Cavern.

Overgrown Cavern

The Overgrown Cavern is a room in the Tallon Overworld. It appears in Metroid Prime. It is a narrow cave filled with rocks and various plantlife, through which a Morph Ball tunnel passes. There is a patch of Venom Weed and a Missile Expansion in the tunnel.

Transport Tunnel C

Transport Tunnel C is a room in the Tallon Overworld. It appears in Metroid Prime. It is a short, cracked, arched tunnel whose walls are green with moss, leading to a larger room that contains a huge Great Tree to one side. The limbs of this tree block Samus's passage through the room, requiring her to jump then use the Morph Ball. Blastcaps around the roots provide the only hazard here.

Transport to Chozo Ruins East

Transport to Chozo Ruins East is a room in the Tallon Overworld. It appears in Metroid Prime. This is a typical elevator room, round and tall; as usual, an Interface Module must be scanned must to activate the elevator before it can be used. Just atop this elevator lies the east portion of the Chozo Ruins.  It can be considered a one-way elevator, in that it cannot be accessed from the Frigate Crash Site due to its entrance being so high in said room, unless special maneuvers are used to climb the crash site.

Frigate Access Tunnel

The Frigate Access Tunnel is a room in the Tallon Overworld. It appears in Metroid Prime. It is a short cave-like tunnel of mossy rock and debris from the crashed Frigate Orpheon. It narrows to a section containing Tangle Weed, then opens out again into a large, round, metal tunnel that leads to the far door. This tunnel is actually part of the Frigate. It crashed through the end of this room during the crash, thus providing entrance to said Frigate.

Main Ventilation Shaft Section C

This room remained intact after the Orpheon crashed into the Tallon Overworld. Rock formations broke through part of the shaft, and function to provide steps for Samus. The bottom of the shaft is flooded, and the huge rock at the bottom is blocking the door to Main Ventilation Shaft Section D. Access to that room is not possible after the crash. An Aqua Sac is visible beneath the glass floor. The water contains a school of 5 Fish. There is a passage leading out of the water that contains some debris that must be circumnavigated using the Morph Ball.

Main Ventilation Shaft Section B

The room remains relatively intact after the Orpheon crashed into the Tallon Overworld. A large rock wall has broken through part of the shaft. Both Auto Defense Turrets are both still active and are in fact stronger than before, but no longer are linked to the door's energy systems. A Sap Sac is found connected to the rock wall. The door leading to the hallway leading to Main Ventilation Shaft Section A was de-energized, requiring Samus to shoot a Power Conduit above the door with the Wave Beam.

Main Ventilation Shaft Section A

After the frigate crashed into the Tallon Overworld, a large portion of the room was flooded. In the unflooded portion, there is a swarm of Tallon Crabs. The flooded portion contains some Fish and a door leading to the Reactor Core.

Reactor Core

Later, when Samus explores the wreckage of the Orpheon she comes across this room again. Now completely underwater, the Reactor Core has multiple floating platforms to get to the top and bottom of the room. The bottom of the room is covered with sand and a bunch of rocks pierce through the room. Several Power Conduits need to be activated with the Wave Beam to energize the door out. This room has Aqua Reapers, 2 Aqua Pirates and a Jelzap after the crash.

Reactor Access

After the crash, the room becomes flooded. The door leading to the Freight Lift becomes de-energized and two Power Conduits must be shot with the Wave Beam to reactivate it.

Save Station

Save Station is a room in the Tallon Overworld. It appears in Metroid Prime. As it is the only Save Station in the Overworld (discounting the Gunship), it is referred in the game as Save Station. This is the only Save Station room in the Prime series to be underwater.

Cargo Freight Lift to Deck Gamma

The room survived when the Frigate Orpheon crashed into the Tallon Overworld. Like the rest of the crashed frigate, the room has become flooded. The elevator has crashed into the bottom of the shaft and is inoperable, and because it is inoperable, there are now platforms floating throughout the shaft that Samus can use to reach the top. If Samus arrives here without the Gravity Suit, a display warns "Power Suit augmentation required to advance", as the water's gravity prevents her from making any further progress into the crashed frigate and is forced to turn back. Aqua Reapers attempt to block the way. When Samus reaches the top, there is an explosion, and a dead Space Pirate falls into the water. If Samus manages to shoot the highest Power Conduit from below, before triggering the explosion, the camera's panning will reveal the Pirate to be dead on a platform (which is what explodes). Though most of the room is flooded, the top is not. The door to Deck Beta Transit Hall lost power, and must be powered by three Power Conduits. The first conduit is next to the elevator door slot. The second is on the side of a wall directly above the elevator. The third is to the left of the powerless door.

Deck Beta Transit Hall

The room survived the Frigate's crash, and now contains some lichen and butterflies, but nothing else of importance.

Biohazard Containment

The room survives the crash into Tallon IV. All of the creatures in storage, except for the dead Parasite Queen, have disappeared, including the creature resembling a Sidehopper. The glass for some of the pods containing these creatures are missing. The bottom half of the room is now submerged in water. The elevator in the room is inoperable and stuck in between floors, and all of the computer screens are broken as well. At the top of the room are two Auto Defense Turrets. At the bottom are two Aqua Drones that are only found on the first visit after the crash, and cannot be found in any other room for the rest of the game. The cell where the Sidehopper-creature was contained now contains a Missile Expansion, and is sealed behind a Cordite door.

The door leading to Deck Beta Security Hall is de-energized, and requires the activation of 3 Power Conduits. The first Conduit is above the stasis tube containing the deceased Parasite Queen. The second is on the wall of the second floor next to the elevator. The final conduit is in the second cell away from the de-energized door.

Upon the second visit to the room, an explosion causes two Space Pirate corpses to drop into the water. Three Aqua Reapers also break open the door to the cell to the left of the Missile Expansion.

Deck Beta Security Hall

The room becomes completely submerged after the frigate's crash, and becomes infested with Aqua Reapers. Also, because of the angle that the frigate crashed at, the entire passageway is tilted. There are glass shards that can be seen floating throughout the hall.

Biotech Research Area 1

The room is completely flooded when Samus returns to the frigate on her way to the Phazon Mines. The room is completely lopsided and contains a large amount of debris. The walkway above the main room is now almost entirely blocked by debris, except close to the doors leading to Deck Beta Conduit Hall and Deck Beta Security Hall. The door leading to Connection Elevator to Deck Beta is blocked by debris. The hatch leading to Subventilation Shaft Section A was closed off by a large door after Samus passes through it. The door remains intact after the crash but is powerless and cannot be reactivated. The hatch covering a shaft below it was destroyed. However, it is blocked by debris. On the first visit, 3 Aqua Pirates are found in the room, but in the second visit, 4 Jelzaps can be found in their place. The door leading to Deck Beta Conduit Hall is de-energized and must be powered by three Power Conduits. The first is on the wall to the right of the door leading to Deck Beta Security Hall. The second is near the open tunnel. The last is directly below the door.

Deck Beta Conduit Hall

Samus returns to the room while she is exploring the crashed Orpheon. It is completely flooded. The blockage that required Samus to use the Morph Ball has somehow been removed. The room contains 6 Aqua Reapers. There are some floating glass shards in the room. The room now looks almost identical to Deck Beta Security Hall.

Connection Elevator to Deck Beta

The Connection Elevator to Deck Beta found while Samus is exploring the wreckage of the Orpheon appears to be the same room. Upon entering the room, the floor explodes, causing a dead Space Pirate to drift upwards. There are 3 Aqua Sacs found in the shaft. The floor below was destroyed, and rocks now puncture the shaft. Wreckage serve as platforms for Samus to use to ascend or descend the shaft. Interestingly, Samus actually goes below the actual elevator shaft to get to the Hydro Access Tunnel.

Hydro Access Tunnel

The Hydro Access Tunnel is a room in the underwater Frigate Orpheon, located in the Tallon Overworld. It appears in Metroid Prime. The room is mostly a Morph Ball tunnel. There is an Energy Tank located on the upper left of the room.

Great Tree Hall

The Great Tree Hall is a room in the Tallon Overworld. It appears in Metroid Prime. The hall has two levels. The first one is partially underwater. The second, upper level is blocked by a barrier controlled by a Spinner that is located on the bottom level. Samus first enters it from a door out of the crashed Frigate Orpheon. As the name implies, there is a the Great Tree in the center of the room which helps Samus reach a higher ledge that can allow her to open up an entrance to the Life Grove.

Great Tree Chamber

The Great Tree Chamber is a room in the Tallon Overworld. It appears in Metroid Prime, and is accessed from the Great Tree Hall. Samus needs the X-Ray Visor to reach this room, as it makes invisible platforms visible, which are used to get to this room.

Transport to Chozo Ruins South

Transport to Chozo Ruins South is a room in the Tallon Overworld. It appears in Metroid Prime. It is an ordinary room containing an elevator, which, to use, Samus must activate by scanning a nearby Interface Module. Just atop this elevator lies the south(east) portion of the Chozo Ruins.

Transport Tunnel D

Transport Tunnel D is a room in Tallon Overworld in Metroid Prime. It is an arched stone tunnel with uneven floor, its walls green with moss, containing Seedlings and Sap Sacs on branches.

Transport Tunnel E

Transport Tunnel E is a room in the Tallon Overworld. It appears in Metroid Prime. The tunnel is named as such because it serves as access to an elevator to the Phazon Mines. The room contains a narrow bridge over Phazon that can cause damage to Samus if she falls in it. When she walks near it, a message saying "Intense radiation detected." will appear on her HUD. This is the only time this happens. In the PAL versions of the game, the Power Suit will also say "Radiation detected."

Transport to Phazon Mines East

Transport to Phazon Mines East is an Elevator in the Tallon Overworld in Metroid Prime, leading downward into the Phazon Mines. This entrance on the east is the Mines' first accessible entrance. Several Red Starbursts can be seen on the walls.

Life Grove Tunnel

Life Grove Tunnel is a room in the Tallon Overworld. It appears in Metroid Prime. This is the only access to Life Grove, where one of the Chozo Artifacts is hidden. The room is an oval shaped tunnel, with two smaller tunnels leading out; the left from Great Tree Hall and the right to the Life Grove.

Life Grove

The Life Grove is a room in the Tallon Overworld. It appears in Metroid Prime. When Samus enters, she finds herself at the edge of a cliff. She must jump down to find herself inside a large dome-like structure, with a small piece of land sticking out of the water. On this land piece is the X-Ray Visor, which Samus will need to exit the Life Grove, and for further progression of events.
