The Main Quarry is a room in the Phazon Mines. It appears in Metroid Prime.
Descrption[]
As its name states, it is one of the main rooms in the Phazon Mines. The atmosphere seems to be largely polluted around the Mines, as seen by the hazy, pink sky and a factory pumping fumes into the air.
A Dual-Control Force Field controlled by two terminals blocks the way to Security Access A. A Spider Ball Track leads to the area's first Save Station.
There is a series of walkways leading up to an area with a Crane, and controls. The crane has a Grapple Point at its end, and can serve as a method of reaching Waste Disposal once the Grapple Beam is obtained.

LeRoy Strauss design notes[]
The Main Quarry took about three weeks to completely model and texture. All game textures for the area were hand done by Mr. Strauss in Photoshop and Painter. "There were a couple of digital photo's used to make a noise layer or for paper in Painter. All textures though were hand made with tons of layers. As far as texture count for each room I don't remember too much. It wasn't the amount of textures but rather that amount of memory we had to stay in," explained LeRoy.
For inspiration on the design of the area, LeRoy looked at a number of source materials to realistically portray the setting. "I looked at many photos of real life places like factories [and] outdoors scenes. As far as inspirations from movies and video games, I was inspired by it all," describes LeRoy. "I love video games and movies, so all that content is up there floating in my head. As to specific movie[s] or game[s], I am not sure. It's just a big jumble of Sci-Fi and fantasy!"[1]
Trivia[]
- By using a Slope Jump on top of the crane, it is possible to reach the door to Waste Disposal early. However, this is not possible on the PAL version of the game as the door is locked until the Grapple Beam is obtained.
- By moving the crane and then moving it back to its original position, the Grapple Point suspended from the crane is able to be scanned for its research entry, even without the Grapple Beam.
- In the Gamecube version, the White Door leading to Security Access A can strangely be opened with the Phazon Beam (via hacking). It shares this trait with a few other White doors found on Tallon IV.
