SR Area 3 Machines

Machines in the background of Area 3.

Area 3 (originally known as Phase 4) is an area of SR388 in Metroid II: Return of Samus and its remake, Metroid: Samus Returns.

It is the fourth area Samus visits on her mission to exterminate all Metroids on SR388.


Phase 4 Purple Liquid

Purple liquid in Metroid II

After Samus defeats more Alpha Metroids and her first Gamma Metroids in Area 2, she is able to visit Area 3 after the purple liquid has drained.

In Metroid II, Phase 4 consists of two parts. When heading right from the central path, the path splits. Going up leads to the third set of Chozo ruins, and heading down leads into an lush area with poisonous plants, vines, restraining Metroid webs, and a hive at the top (two rooms filled with honeycombs).

In Samus Returns, Area 3 has been expanded from the original and now has a big focus on Chozo robotics. The area features more Chozo ruins and has been turned into a mining industrial complex with working pistons visible in the background. This area has the most robotic enemies out of all areas, and there are many Chozo mining robots out of order in the background. Area 3 is where Samus accidentally awakens the Diggernaut, which attacks her later during her mission.

The items obtained in Phase 4/Area 3 in Return of Samus and Samus Returns are very different. In Return of Samus, Samus obtains the Space JumpSpazer Laser Beam and Plasma Beam, while she only obtains the Grapple Beam and Beam Burst Aeion ability in Samus Returns.
