Metroid Prime/Missile Launcher

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

Landing Site
Scan: Gunship Radio-active ferns



This is the location of the Gunship throughout the rest of the game. You can return here to replenish your energy, all ammunition, and save the game. The Landing Site has multipld doors that you can take, however you do not have the necessary equipment to progress through most of them so take the door to the right of the Gunship.

Canyon Cavern
Scan: Beetle

Shortly after you approach the sand in this room you'll be attacked by a pair of creatures called Beetles. You can find these often throughout several parts of Tallon IV, so don't worry if you neglect to scan them.

Tallon Canyon


Scans: Sap Sac, Blastcap, Zoomer, Geemer

There are multiple Log Book entries you can get in this room. The first is the Sap Sac, an explosive plant. After further progression into the room, you'll find Blastcaps located in the water. If you touch these, they will explode so exercise caution. On the rock face on the left side you can find Zoomers and the right you can find a single Geemer.

There are multiple doorways in this room however like the Landing Site you cannot progress without more equipment. Take the door to Transport Tunnel A then to the Transport to Chozo Ruins West.

Path: Transport Tunnel A, Transport to Chozo Ruins West, Transport to Tallon Overworld North, Ruins Entrance

Ruins Entrance
Scan: Chozo Lore - Fountain (NTSC)/ Beginnings (PAL/Trilogy)

Above the door to the Main Plaza, you can find your first bit of Chozo Lore.

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.
