Tallon Overworld

Tallon Overworld is the area where Samus lands on planet Tallon IV after leaving the Space Pirate frigate Orpheon during the events of Metroid Prime. The area links to every area on Tallon IV except for the Phendrana Drifts. It also contains the crash site of the Orpheon and the Artifact Temple.

Geography
Tallon Overworld is a watery place with many plants, and is often under heavy rainfall. It is swamp-like in some areas, but most remains a wet jungle, with many large rooms. Tallon Overworld is essentially a linking sector to all the other areas of Tallon IV except for the Phendrana region, which can only be accessed via Magmoor Caverns. Zoomers, Geemers, and Beetles make up the bulk of the area's bioforms. Tallon Overworld is also where Meta Ridley is fought, guarding access to the Impact Crater. Tallon Overworld has at least one elevator connecting to every area in the game (aside from the afformentioned Phendrana Drifts) and it is the only area to have this feature.

Areas and Main Rooms
The Tallon Overworld can be divided into four areas:

North Area
The main area in the region. It contains also the Transport to Chozo Ruins East and its accesses. It is in this area where Samus finds the Space Jump Boots.

South Area

Trivia

 * Before Samus has acquired the Spider Ball upgrade, the music featured in this area is a remix of the original Brinstar theme from the first game, Metroid. However, it changes to a remix of Brinstar's theme in Super Metroid afterward.
