Kraid entrance shaft[edit | edit source]

Main article: Kraid entrance shaft

Kraid's Lair-Brinstar elevator.png

"Kraid entrance shaft" is the first room in Kraid's Lair. It appears in Metroid and Metroid: Zero Mission. In Metroid, the room is constructed out of white blocks that appear to be comprised of bricks, which are held together by rock-like black blocks, and lined with small green bushes. Along the shaft are two midair platforms and at least two ledges on either wall. The barrier at the bottom of the room has a hanging pillar in front of it. It can be ascended from the other way with Bomb Jumps. Should Samus fall to the bottom of the shaft, she can ascend it by strategically freezing Rippers along the lower shaft and using them as platforms. This room contains 7 Zeelas and 4 Rippers.

Baristute pit[edit | edit source]

Main article: Baristute pit

Baristute pit Metroid.png

The "Baristute pit" is a room in Kraid's Lair. It appears, with significant differences between versions, in Metroid and Metroid: Zero Mission. In Metroid, the room is divided into two parts: a square alcove on the right, and a corridor on the left. It is divided by a wall of blue bricks, with two tunnels that Samus can pass through in her Morph Ball. The tunnels have a small number of Bomb Blocks in them. The alcove has little to speak of in terms of features aside from a small pool of acid and an Air Hole that indefinitely spawns Geegas. This provides Samus with an opportunity to refill her energy and Missile Ammo by killing each Geega that comes out. Through the wall is a longer corridor with a larger pool of acid and two more small ones. Above the larger lake is a group of seven midair pillars that are spread out, and a Missile Tank is atop the center. In the middle of the room is a raised section of floor with another Air Hole, and before the exit on the left are a pair of acid pools and two pillars on the ceiling, and one on the floor. A lot of enemies are found here, and the close quarters nature of the room makes it tricky to navigate unless Samus is prepared.

Main article: Caged Sidehopper hall

Caged Sidehopper hall Metroid.png

The "caged Sidehopper hall" is a room in Kraid's Lair. It appears, with differences between versions, in Metroid and Metroid: Zero Mission. In Metroid, this shaft's floor is filled with acid and can only be safely navigated through a series of small platforms in midair. The platforms eventually give way to a group of seven midair pedestals that are spread out like stairs. Atop the central one is a Missile Tank. Should Samus fall in between the pillars, she can morph and roll underneath them in the acid to escape, assuming she has enough energy to survive. Beyond the pillars is a small alcove of dry land, with one small gap in the floor containing acid. The left side of the room features wall tiles that resemble blue rings with a light blue center. The ceiling above the pedestals is composed of tiny metal tiles, while the rightmost side of the room is made of blue brick, chain and solid tiles.

Apex launcher shaft Metroid.png

The "apex launcher shaft" is a room in Kraid's Lair. It appears, with significant differences between versions, in Metroid and Metroid: Zero Mission. In Metroid, this room is optional and does not need to be explored. It does not lead to any expansions, or more importantly, Kraid. It is constructed from white brick tiles and black rock tiles, with green bushes growing out of the walls. The shaft is ascended using multiple midair blocks and ledges mounted on the walls, many of them containing Zeelas. There are four doors on the left side of the shaft, including the entrance. The upper three lead into identical corridors. This room has 10 Zeelas.

"Kraid's highest corridor" is a room in Kraid's Lair. It appears, with significant differences between versions, in Metroid and Metroid: Zero Mission. In Metroid, this room is optional and does not need to be explored, seeing as it does not lead to Kraid or any expansions or power-ups. It is one of three identical corridors between the "apex shaft" and "Zeela-infested shaft", containing the same enemies. The room is constructed from blue bricks and tiles, with three pits of acid in the floor and two Air Holes in the floor, and three silver pillars near the left side.

The "acidic concourse" is a room in Kraid. It appears, with significant differences between versions, in Metroid and Metroid: Zero Mission. In Metroid, the corridor is constructed from blue bricks and tiles. It is long and has five Air Holes in the floor, as well as three thin acid pools. A large portion of the floor in the center of the room is raised; three of the Air Holes are found here. The room is infested with Sidehoppers, which makes navigation difficult unless Samus has the Screw Attack. Near the left side of the room are three metal pillars, one in the floor and two hanging from the ceiling. This is one of two corridors Samus can take to reach the lair's leftmost shaft.

The Bottomless Pond is a room in Kraid. It appears, with significant differences between versions, in Metroid and Metroid: Zero Mission. In Metroid, the shaft is comprised of grey and black blocks, the latter of which appear to be made of rock, and pillars. The walls are lined with green bushes. Only two ledges and two platforms exist in the initial shaft, along with a pool of fake acid below. Through this is a longer shaft filled with multiple Rippers. Unless Samus has the Ice Beam and can carefully freeze and use the Rippers as Ice Beam Platforms#platforms, it is difficult to re-ascend the shaft. At its bottom is a single midair platform, a ledge on the right wall, and a floor above an inaccessible pool of real acid. The door at the base of the shaft leads toward Kraid's room. The room contains 15 Rippers and 2 Zeelas.

Kraid Antechamber Metroid.png

The "antechamber" is a small room accessible from the base of the Bottomless Pond shaft. The room has no unique features, simply consisting of a passage in between a narrow ceiling and floor made of blue blocks. It leads into the mostly identical Drain. One Sidehopper inhabits this room.

Drain[edit | edit source]

Kraid Drain Metroid.png

The drain is a small room nearly identical to the previous antechamber, and connects from that antechamber to the "ball launcher speedway". The difference between this room and the antechamber is the presence of a secret tunnel (referred to as a drain in the strategy guide[1]) in the floor directly underneath the door to the antechamber. This leads into a small chamber attached to a hallway where Mini-Kraid is found. A single Sidehopper can be found here, just like the previous room.

Fakekraid.jpg

"Mini-Kraid's room" is a room in Kraid. It appears in Metroid and Metroid: Zero Mission. In the former game, it is the location of Mini-Kraid, who is absent from Zero Mission. Another version of this room appears in Super Metroid, where it is part of Brinstar. In the original Metroid, this room is actually comprised of two rooms, each constructed from green blocks and other tiles resembling fencing. The first is a small, square room with a pillar and a raised ledge with the exit, and is entered through a hidden "drain" above. A single Sidehopper can be found here. Through the door is a longer corridor with three pillars installed in the floor, four Air Holes embedded in the floor (which spawn Geegas) and a small pool of acid near the exit which also spawns infinite Geegas, two at a time. Mini-Kraid is found in this portion of the room as a regular enemy. When killed, nothing happens, leading many first-time players of Metroid in 1986 to believe they had killed the real Kraid. Visiting this room is not required to reach Kraid and is one of many paths Samus can take to reach him.

The "ball launcher speedway" is a room in Kraid. It appears, with significant differences between versions, in Metroid and Metroid: Zero Mission. In Metroid, the room is similar to other horizontal corridors in Kraid's Lair. Its walls and ceiling consist of spherical blue tiles, and much of the floor is engulfed in a lake of acid. Samus must cross the room using multiple midair platforms. A group of pillars, fanned out as if they were steps, are present near the left side; atop the center pillar is a Missile Tank. Near the exit on the right is a wide platform in the acid with a single Air Hole spawning Geegas. The room is infested with enemies, but is one of several paths Samus can take to get to Kraid.

The "Sidehopper infested hall" is a short corridor found through the bottom left of the entrance shaft. Due to memory issues, it shares an identical appearance to five other hallway rooms in Kraid's Lair. Its inhabitants include four Shriekbats, Geegas spawned from two Air Holes, and a Sidehopper. More Sidehoppers were added to the room in Zero Mission, hence the name.

The "pipe shaft" is a tall shaft on the western side of Kraid's Lair. It does not need to be explored, but is one of several optional paths to Kraid himself. Because of memory limitations, it is identical to the Zeela infested shaft elsewhere in Kraid's Lair. Both rooms contain six Zeelas and three Rippers. A glass pipe was later added to this room in Zero Mission, hence the name.

"Kraid's gauntlet" is a room in Kraid. It appears, with significant differences between versions, in Metroid and Metroid: Zero Mission. In Metroid, the gauntlet is a short corridor identical to five other hallway rooms in Kraid's Lair. The repetitive appearance of this room is likely due to memory limitations. The corridor has a partially low-hanging ceiling, three acid pits and two Air Holes in the floor, and three pillars in the ceiling and floor. It is one of several optional paths Samus can take to reach Kraid.

In Metroid, due to memory limitations this room is identical to several other corridors found in Kraid, such as what would later become the "Acid Worm's room" in Zero Mission. Its tiles consist of blue bricks and blocks, with three acid pits in the floor, two Air Holes that spawn endless Geegas, a ceiling overhang and three silver pillars near the left side. Because there is a shortcut in "Kraid's room access", Samus does not need to visit this room to get to Kraid.

In Metroid, this room is a small chamber with a blue bridge over a pool of acid. Geegas spawn endlessly from the acid, providing an opportunity for Samus to replenish her energy and Missile Ammo by shooting them. The ceiling consists of green tiles, with two red orbs and twelve downward spikes arranged to resemble a creature's maw. A similar face appears in "Mini-Kraid's room" in Super Metroid.

Kraid's Lair Energy Tank 2.png

Kraid's room is the room where Kraid is battled in his lair. The chamber is different between its appearances in Metroid and Metroid: Zero Mission, and Super Metroid. In the original Metroid, Kraid's room is constructed from blue and silver architecture. The ceiling of the room features silver spikes and red orbs, arranged in a manner that resembles the teeth and eyes of a large creature; a similar structure appears in the room just outside his chamber, as well as in Ridley's room.

The room is locked behind a Red Hatch. Kraid resides on a platform in the center of the room, with small pools of acid on either side. Unlike any of its later appearances, the layout of this room does not change at all during the boss battle.

Block column shaft Metroid.png

The "Block column shaft" is a room in Kraid's Lair/Kraid. It appears, with differences between versions, in Metroid and Metroid: Zero Mission. In Metroid, this is a very tall shaft constructed from grey and black blocks of rocky materials and brick. It is challenging to ascend, as only a few small midair platforms exist in the shaft and are too far apart for Samus to reach even with the High Jump Boots. To ascend the shaft, she must make use of a large column of Fake Blocks by shooting some out, and jumping repeatedly. She can continue gradually shooting blocks above her, and jumping before those below her regenerate, to climb the shaft. At least four solid platforms are positioned along the column for Samus to jump to if she needs a break, or as insurance in case a block regenerates over her. When this happens, Samus takes damage and is knocked back, potentially sending her flaling to the base of the shaft. Once at the top of the column, Samus can exit into a door near the apex of the shaft, leading back to the elevator.

The "acid fall" is room in Kraid. It appears, with significant differences between versions, in Metroid and Metroid: Zero Mission. In Metroid, this is a simple corridor that reuses certain assets found elsewhere in Kraid. The rightmost part of the room consists of blue brick-like tiles with the entrance door on a ledge, and a blocky overhang from the ceiling in front. A single Air Hole and small fissure filled with acid is found here. To its left is a wider pool of acid with pillars forming a "staircase" of sorts. A Missile Tank can be found on the middle pillar. This is the primary reason for coming to this room. The wall on the left is made of white bricks and black rocks, and is part of the ceiling for a different room.

The "corrosive pool" is room in Kraid. It appears, with significant differences between versions, in Metroid and Metroid: Zero Mission. In Metroid, the room's appearance very simply consists of blue circular tiles in the ceiling and walls. Thirteen platforms exist above the acid, which Samus can use to safely cross the room. Complicating this are Geegas that repeatedly spawn from nine points in the acid. Zeelas and Sidehoppers are also present here, making the trek difficult unless Samus has the Screw Attack and/or the Ice Beam.

The "acid-filled runway" is a room in Kraid. It appears, with significant differences between versions, in Metroid and Metroid: Zero Mission. In Metroid, the corridor is constructed from multiple tilesets, including blue and circular near the entrance and white and black near the end. The initial room is a square chamber with three midair platforms and a pool of acid below, from which an infinite stream of Geegas spawns. There are two passages in the large wall to the right that lead to a secret second half of the chamber, with another small acid pool and three midair pillars above. An Energy Tank is found in between the pillars, in plain view. As is typical of item corridors, the ceiling above the item itself is made of small white tiles.
