See here for the room's equivalent in Metroid. This is the only Save Room in Ridley that repurposes an existing room from the original game.

Connecting rooms

:• Pronged hall (Blue Door)
:• Path over lava (Blue Door)
==Pronged hall==
The "pronged hall" is a short room located between the upper left half of the Artificial Passage and the shaft of doom. Half of the room's ceiling and floor is grey, and the other is green. Two partially collapsed pillars, a common fixture throughout Ridley, are present in the background. It is divided in half by a large wall with a Bomb Block at the base on each side.
Destroying these releases a large group of Multiviolas, which can overwhelm Samus if she does not kill them quickly. Rolling into the wall through the openings reveals that it is illusionary, and only a pair of ceiling pillars ("prongs") remains. Samus can use this room to get to the other side of the Artificial Passage for its Energy Tank, if she fell through the false floor.

Items
:• Missile Tank
Connecting rooms
:• Ridley's rightmost shaft (Blue Door)
:• Multiviola Nest (one-way drop)
:• Cache 1 (Blue Door)
==Cache 1==
"Cache 1" is a small room located between the middle corridor and the upper gambit shaft. It did not previously exist in Metroid. much of the room's walls consist of damaged grating, with multiple torn holes throughout them. When Samus enters the room, she must climb over a wall in Morph Ball form and roll into a constricting tunnel, atop which is a pedestal with a Missile Tank. Laying a Bomb removes a row of destructible blocks and allows Samus to access the tank. The item is surrounded by four Multiviolas. After this, Samus can jump to a ledge on the left and destroy a pillar above with a Bomb, then jump up two more ledges to reach a tunnel obstructed by a Super Missile Block. Through here is a midair cube made of Bomb Blocks, which explode in a spiraling pattern when detonated. The very last block contains a Super Missile Tank.
==Gambit shaft==
The "gambit shaft" is a room in Ridley's Lair. It appears, with differences between versions, in Metroid and Metroid: Zero Mission.
Items
:• Missile Tank
Connecting rooms
:• Cache 1 (Blue Door)
:• Cache Access (Blue Door)
:• Save Room 4 (Blue Door)
:• Sloped passage (Blue Door)
==Cache Access==
"Cache Access" is a straightforward corridor, accessible from the gambit shaft. Unlike the original game, it is most likely visited from that room first, rather than the other way around. The door that led into it from the Artificial Passage has been removed, and it leads into Cache 2. In terms of appearance, the lower part of the room is filled with lava, although it poses no threat to Samus. Her primary obstacle in the room is a group of Dessgeegas.
See here for the room's equivalent in Metroid.
==Cache 2==
"Cache 2" is another new room in Zero Mission. It contains two expansions, including a Super Missile Tank in plain sight. Once Samus collects it, she can jump into a hidden ledge in the right part of the ceiling which is lower. This is revealed to be an illusion disguising a pillar-like ledge. Samus can morph into a small crevice between the pillar and the ceiling to find a path to an upper part of the room. Shooting a block directly above Samus reveals a Missile Tank. After this, she can continue into the next room.
==Cache 3==
"Cache 3" is the third and final cache room in Ridley. This room features two midair block platforms with thin gaps around them, some of which Samus can only fit into with her Morph Ball. It contains two Missile Tanks. The first Tank is the easiest to acquire, first by shooting Fake Blocks in the side of the first midair platform and rolling under it, then jumping atop the platform. Samus must then fall down the right side of the platforms, quickly shooting into the wall underneath the door to expose a Fake Block in front of the second tank. She must quickly grab the ledge before she falls through a pair of Pit Blocks directly underneath, and roll into the crevice with the item. Should Samus fall through the Pit Blocks without collecting it, she can make use of a Morph Ball launcher in the bottom right corner of the room to blast back up to the top, and try again. She can also use it after collecting the item in order to get back to the exit and leave.
==Sloped passage==
The "sloped passage" is a new room in Zero Mission. It is a long corridor between the lower gambit shaft and the Multiviola Nest. As the name implies, there is a large hill in the floor that descends into a slope. A large wall is found on the right side of the room, with its lower half partially made of Boost Blocks. The upper half is barricaded with Fake Blocks, allowing for passage from the other side and so that Samus can still get through this room if the Speed Booster is skipped. Within the Boost Block wall is a group of Holtz, Violas and Multiviolas clustered together. By running through the room with the Speed Booster active, Samus will blast through the lower wall and destroy these enemies with ease.
==Multiviola Nest==
The Multiviola Nest is a room in Ridley's Lair in Metroid and Metroid: Zero Mission.
