Matter Decompressor
Matter Decompressor is a megastructure in Stellaris 4.5.2 built in 5 stages. Must be built in a system with a black hole and no habitable planets. It needs the Matter Decompressor technology. All stages take 45 years and 17,500 Alloys, 25,000 Unity (the costs every empire pays). Matter Decompressor produces 2,000 Minerals a month.
Where to build a Matter Decompressor
The game's own requirement line, then the conditions of the first stage (possible) and of the planet or star it goes around (placement_rules).
Must be built in a system with a black hole and no habitable planets.
- Must build around a star.
- Cannot build on planets that have unresearched anomalies discovered by us or any other Empire.
- Star class: Black Hole
- The system has a starbase
- Cannot build outside Empire borders.
- Cannot build in systems that have not been surveyed.
- Cannot build in systems with habitable planets.
- Requires a Black Hole in the system.
- Cannot build more than one Matter Decompressor.
- Cannot build more than two Matter Decompressors.
- Cannot build due to existing Megastructure.
Matter Decompressor stages
Cost lines with a condition apply only to the empires it names (bio-ship empires pay food instead of part of the alloys).
How it's counted
Totals in the head count only the costs every empire pays: 17,500 Alloys, 25,000 Unity.
Matter Decompressor Site
The construction site station serves as the base for the future construction of a Matter Decompressor: Anchor.

The gravity lensing facility redirects a portion of the black hole's gravitational force, concentrating it even more strongly in a selected area.

The ultimate refinement of the gravity redirection system forms a focused area of twisted gravity, creating a vast drill whose bore is made of redirected and concentrated gravitational force.

With a bore of twisted gravity tunneling into the singularity and a series of automated matter decompressors, processors, and smelters in orbit, we are able to extract minerals from a black hole.

Other versions of the Matter Decompressor
Ruins the galaxy can start with or a war leaves behind (restoring one is its own chain of stages) and upgrades that branch off the main line.
Ruined Matter Decompressor (permanently ruined)
Ruined Matter Decompressor
An orbital station in severe disrepair, this Matter Decompressor once skirted natural law by reclaiming matter from the black hole in this system. It is now damaged beyond all repair.
