Area 2 (originally known as Phase 3 in Nintendo Power) is an area of SR388 in Metroid II: Return of Samus and its remake, Metroid: Samus Returns.

It is the third area Samus visits on her mission to exterminate the Metroids of SR388.


After the four Alpha Metroids of Area 1 are defeated, the purple liquid drains, giving Samus access to Area 2. This area is again set in a Chozo settlement within a large cavern, and is the area where Samus encounters her first Gamma Metroids. The boss Arachnus is also encountered here, disguising itself as an Item Sphere in the Chozo ruins.

In Return of Samus, the Phase 3 Chozo ruins contain several long narrow vertical pipes, which Samus can climb using the Spider Ball to access different rooms in the complex. The large cavern has a pool of water, which has also flooded some of the lower rooms of the ruins. A pair of Blob Throwers, the only specimens in the game, have taken root atop the roof of the Chozo settlement.

Phase 3 is also home to catacombs very similar to those previously found in Phase 2, which are infested with Metroids and overgrown with bushes. Additionally, some of these caves are filled with sand, which Samus must clear away with her beam weaponry in order to navigate. It is in these tunnels that Samus encounters the first two Gamma Metroids.

In Samus Returns, the area has been turned into what resembles a hydroelectric power station built around natural caverns filled with water. There are large lava and water streams being held back with Chozo technology in the background. The largest room of Area 2 consists of a large water dam, with artificial waterfalls and many stalactites hanging from the ceiling. Area 2 has many underground geysers, and there are many large non-hostile creatures that live in the damp caverns. The lowest points of Area 2 contain many volcanoes that are presumably the cause of these geysers.

In both games, Samus obtains the High Jump BootsVaria Suit, Wave Beam and Spring Ball from Arachnus. In Samus Returns, she also obtains the Lightning Armor Aeion ability.

In Samus Returns, the theme that plays in the entrance of the area is internally named Area4 5 Basic. It may be a remix of the ambient theme that originally played in Phase 3 in Return of Samus.
