Red Door (Metroid Prime)
A Red Door is a type of Door found in Metroid Prime. They are the least common among all types of Doors that are encountered during Prime, mostly being found during Samus' mission in the Phazon Mines. They are opened with one blast of the Plasma Beam, of which they share a similar texture.
This Door's purpose is the same as that of the Orange Door in Metroid Prime 3: Corruption. A similar Door also appears in Metroid, Metroid II, Super Metroid, Metroid: Zero Mission, and Metroid Prime 2: Echoes named the Red Blast Shield, and the Red Blast Shield's counterpart in Metroid Prime is the Missile Door Lock. Another Red Blast Shield appears in Metroid Prime Hunters.
