Shaft of doom

The "shaft of doom" is a room in Ridley's Lair/Ridley. It appears, with differences, in Metroid and Metroid: Zero Mission.
==Description==
This room is a tall shaft found on the west side of Ridley's Lair. 
 From here, there is a short ledge and a somewhat long drop to the bottom of the room. An Air Hole can be found on the bottom left, which spawns Zebbos indefinitely and is a good spot to replenish energy and Missile Ammo. Samus can also lure out a Zebbo and freeze it to use as a platform and re-ascend the shaft. Otherwise, a Red Hatch on the right wall leads into the Map Room.
To get to the new room with expansions, Samus must run into the base of the shaft from the adjacent Zebbo Nest with her Speed Booster activated. This opens up part of the floor, which is made of Boost Blocks, under which is another short shaft leading to the door below. After Samus comes back from this room, she can Shinespark up through the floor to get back into the shaft.

;158 missile tank (pg. 64)
:"Once the Energy Tank [in the Artificial Passage] is yours, record your progress in the save room nearby, then move on to the lair's lower-left region. As you roll, jump and shuffle through the middle of the left shaft, you'll grab a Missile Tank."
;159 STOCK UP ON PICKUPS (pg. 64)
:"The pipe in the shaft's lower-left corner spits out enemies three at a time. Stand a few blocks away from the creature-hatcher, defeat the enemies that pop out, then collect the energy and missiles that they leave behind. Repeat the process until your tanks are full."
;160 MAD DASH TO AN UNMAPPED AREA (pg. 64)
:"To the right of the map room, you'll find a long flat walkway near the ceiling [in the Zebbo Nest]. Go to the right end then run left to build up your Speed Booster. Kneel to stop, drop to the ground and jump over the gap to the left while maintaining your charge.
:Open the hatch, tap A to hop up, then hold left to blast off."
