"No Man's Sky" is a vast, endless universe, full of skies to explore, planets to catalog, and alien mysteries to unravel. But none of that matters. Because one astronaut has spent the last few years building a neon metropolis at the bottom of the ocean and has finally completed it.

This weekend, NMS explorer Chong Sparks put the finishing touches on the project he has been working on for a year and a half.

Chongsparks had initially been quietly piecing together this undersea metropolis without much of a master plan other than to build on the ocean floor. Old tweets reveal that he simply began by stacking the base buildings, haphazardly adding additional rooms, pipes, passageways, and layers of decoration as each new session began.

"I always pick the location first and let the landscape decide what to build," Chong Sparks told us at DM. 'Then ideas are born, and the base grows almost by itself. Sometimes there are plans, but those bases usually end up going nowhere."

"If you're a big fan of the idea, then you're not going to be able to get a good idea of what you're going to build.

If you are tempted to visit the site, Chongsparks offers glyph code (an arcane system for teleporting through the NMS galaxy, which can be seen in the header image). However, he warns that due to the tricks used to build beyond the game's object limits, visitors will not be able to experience the construction in its staggering totality.

Only a small portion of the place can be seen because the roughly 1,500 objects ("beyond a guess") push the facility up to No Man's Sky's build point limit. Basically, NMS assigns point values to objects based on complexity, with the public base capped at 3000 points. However, the community has developed many tricks to maximize this real estate.

"A good builder will consider many things to expand what the NMS can do. Planet types (dead worlds are best), avoiding high point building parts... These are some of the things they consider. In addition, they all use brilliant and creative glitches.

It is tricks like these that allow NMS to build anything from the Doom E1M1 to the Notre Dame. But there is something quietly admirable about entering from a blank canvas and feeling out the base until the giant neon spreads out.

Besides, even if Chongsparks were the only person to swim entirely around it, one could still enjoy the kind of stunning photography that No Man's Sky has always excelled at.
