Metroid Prime/Missile Launcher

Welcome to Tallon IV, where the remainder of the game is set.

Landing Site
The valley in which your ship has landed is lush, green, and very wet. You might as well start by turning around and scanning the ship. This will be a kind of home base for the rest of the game; you can return here to replenish your energy and ammunition, as well as save your progress.

If you check the map you will notice there are actually five doors here, but at the moment you do not have the necessary equipment to reach two of them, and with two others you are unable to get through the next room. The only path where are can make progress is through the door at the top of some ledges to the right of the ship. If you have the hint system on then the game will eventually point you in this direction.

Canyon Cavern
This is a small cave with a sandy floor. Beetles come up out of the ground when you go in but they are easily defeated by you Power Beam weapon. Get the scan first if you're collecting though. The entrance and exit look very similar so if you get turned around just remember to keep the mushrooms on your left.

Tallon Canyon
There is a variety of wildlife in this canyon so get your scan button ready. First get the the bright orange pod on you left, a Sap Sac. It's harmless unless you attack it at short range. Follow the stream to some platforms and notice the mushrooms below them. These are Blastcaps; if you touch them they will explode and if you shoot them from a distance they leave a poisonous gas behind. There are Zoomers on top of the platforms; they are easy to defeat but harmless unless you touch them. On the ledge to the right you can find a single Geemer which is similar, but with tough armor so you can't actually do anything to hurt it now.

You could follow the platforms and ledges to a door, but you won't be able to get much further until later in the game, so just go through the U-shaped passage to the right of the platforms, watching out for the Beetles that live there. The door to the next room is at the far end.

Transport Tunnel A
There are Zoomers and Sap Sacs here.

Transport to Chozo Ruins West
These transports are used to move between the areas of the game. Scan the control panel to activate it and step into the hologram ride as in the frigate elevators. These go much faster though and the distance is great enough that you get a little cut scene showing your trip.

Chozo Ruins
In contrast to the Tallon Overworld, this area is sandy and desert-like. Any water that exists here is poisoned.

Transport to Tallon Overworld North
This is where the transport from Tallon Overworld takes you. If you have the hint system turned on then the game will point you to your next destination sometime after reaching this point.

Ruins Entrance
This is the entrance to what was once the Chozo citadel, now abandoned. Beetles attack when you exit the tunnel from the transport.

After dealing with the beetles, look around and find the inscription above the door to the next room. Scan it to get your first bit of Chozo Lore. These inscriptions are common in this area but you can also find them in other areas as well. They have backstory information on the Chozo civilization and what happened to it.

Main Plaza
Continue past the swarm of Beetles, climb the stairs, and take the door on the left to the Nursery Access.

Nursery Access
Scan: Scarab

A large amount of creatures called Scarabs drop themselves in your path, with touching a single one will only inflict minor damage, walking through the entire swarm will be dangerous for you current levels of energy. Just fire at them to clear yourself a path.

Eyon Tunnel
Scan: Eyon

The Eyons are immune to the Power Beam so you will be unable to destroy them. The flash of the weapon will cause them to shut, ceasing the energy beams along with it.

Ruined Nursery


Scans: Chozo Lore - Exodus (NTSC)/ Harmonization (PAL/Trilogy), War Wasp, War Wasp Hive

After recording the Chozo Lore, you can find two more Log Book entries: War Wasp Hive on the ceiling, and War Wasps which will attack when you approach their hive.

If you need energy or wish to save, the highest door in the room leads to a Save Station, otherwise continue to the North Atrium.

Ruined Gallery
Stay on the upper section of the room and continue on.

Totem Access
Scans: Plazmite, Large Energy, Tangle Weed

The water in this room is toxic, so be careful not to fall into it.

Hive Totem
Scans: Hive Mecha, Ram War Wasp, Missile Lock Door

Go to the central platform in the room and approach the Missile Launcher. Before you can reach it the room will fill with toxic water and the Hive Mecha will protect the launcher.

Boss battle: Hive Mecha


The Hive Mecha's only form of defense is Ram War Wasps. This variety of wasp circles around you then attempts to ram you into the toxic water, so exercise caution. Be sure to scan both the Hive Mecha and the Ram War Wasps, you will be unable to encounter either again.

You'll be able to destroy the Hive Mecha by firing at the access ports that the War Wasps are released from. These are only vulnerable after you destroy all wasps that have already been released. After one is destroyed, the next port will release a larger amount of wasps until all three ports are destroyed. Once defeated, the water level will lower and you can claim your Missile Launcher.

Transport Access North
You can find your first Energy Tank here. It'll increase your energy capacity by 100 units and completely heal you in the process.
