— Description, Sonic the Hedgehog CD[1]

Quartz Quadrant (水晶の象限[1] Suishō no Shōgen?) is the fourth Round in Sonic the Hedgehog CD. It consists of a cave region full of crystals, located on Little Planet. As with the other Rounds in the game, Quartz Quadrant consists of two Zones and a third, shorter Zone that features the Round's boss.

Description[]

Present[]

In the present, Quartz Quadrant is a purple-colored mine bustling with machinery located in Little Planet, and filled with crystals and conveyor belts. Some of the crystal is being transported while some are left lying around. Outdoors, some brown mountains with vegetation and a lake adorn the region's background.

Past[]

In the past, Quartz Quadrant is a green, peaceful cavern where a very large quantity of crystals are lying in a type of ooze. Outside the cavern, a swamp/bayou is seen showing dead driftwood in a lake with green vegetation and purple mountains in the background.

Future[]

Bad[]

In the bad future, Quartz Quadrant is an over-mechanized, olive-green rusted mine under Dr. Eggman's influence where there are no crystals in the mines. A river of what appears to be lava or melted crystals runs through the bottom of the Round, with lots of machines near it. Outside the mines, miles of factories can be seen in the background, polluting the air in a red-orange sky.

Good[]

In the good future, Quartz Quadrant is an underground, green-colored utopia with glowing buildings hidden inside the Round's underground caverns. All of the mining has ceased by this point and opulent towers of crystals gleam through the darkness. Outside the mines, some futuristic, turquoise domes appear in the background, with mountains and forestry beyond them. A wall is seen at the mid-height section of the Round featuring the same type of domes. There are no active mines or swamps here in this timeline, but more crystals are found here than in any of the timelines.

Story[]

Having invaded Little Planet, which includes Quartz Quadrant, Dr. Eggman would install robot teleporters in the past and infest the region with Badniks. He would also put up some Metal Sonic holograms to terrorize the Animals that live there. Using these elements, Eggman managed to conquer the future of the planet and rewrite history in his own image. As such, Quartz Quadrant would be turned into some kind of cylindrical-shaped factory in the future, whose actions would pollute Little Planet and devastate nearby regions.

After Sonic the Hedgehog arrives in the region, he manages to re-write Quartz Quadrant's history and revert Eggman's effects in the region. He also ends up battling Eggman in a trap room deep inside Quartz Quadrant. Unfortunately for the doctor, Sonic manages to defeat him, prompting him to retreat.

Gameplay[]

Quartz Quadrant is a rather expansive level with many different routes the player can take. The main gimmick of Quartz Quadrant is the abundant use of colorful conveyor belts that either speed up or slow down Sonic when running with or against them, respectively, and can change their direction via large switches placed throughout the level. Some paths in level also feature vertical tunnels made out of these conveyor belts that can be used to shoot the player up or down to the next floor, depending on where the conveyor belts are travelling. A common set piece in Quartz Quadrant is its long, empty hallways that periodically break up the upper floors of the Round, often separated by red springs that launch the player over to the other side.

Boss[]

Main article: Egg Conveyer
Boss 4 Good Future

Sonic battling the Egg Conveyer in the good future, from Sonic the Hedgehog CD.

The boss of Quartz Quadrant is the Egg Conveyer, a long, tube-like mech which Dr. Eggman sits in as he tries to attack the player. A conveyor belt runs along the floor and pushes the player into electrically charged spikes. The goal of this battle is to survive the bombs thrown by the doctor until his machine eventually destroys itself.

Robot transporter locations[]

  • Zone 1: A robot transporter is located in the first half of the Zone, at the top part on some platforms. The player should look for a set of three yellow Springs in a moving platform. This one is located near a Kemusi. Bouncing onto the Springs should take the player to the machine.
  • Zone 2: The robot transporter of this Zone is located in the second half of it. In the bottom part of the Zone, the player should look for a vertical tunnel that makes use of conveyor belts. Jumping into it should launch them into the air, destroying the robot transporter instantly.

In the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics, Quartz Quadrant is a Zone located on Little Planet. Its history is basically the same as its video game counterpart.

Trivia[]

  • The "B" Mix of the Quartz Quadrant theme (specifically, the Japanese version) notably features a vocal sample (named "1-09 Tekno_House") that was taken directly from the sample CD album "Polestar Magnetics - The X-Static Goldmine". It is notably a digitally modified sample of Gene Simmons saying "We're gonna get this place (hotter than hell!)", taken from a live performance of KISS playing "Hotter Than Hell" during 1975. This specific recording was included in their album "Alive!" The QQ song also uses the "1_09 Tekno_House" and "1-11 Clonk" samples from the Polestar album.
  • "Quartz Future" from the American soundtrack of Sonic the Hedgehog CD was remixed for the N'rrgal Colony in Sonic Chronicles: The Dark Brotherhood.
  • "Quartz Quadrant "G" mix" from the Japanese soundtrack of Sonic the Hedgehog CD was used in early and playable builds of the cancelled Sega Saturn game, Sonic X-treme.
