The view from a ledge, taken by the M.E.G second climbing attempt on 520.1
Level 520.1 is a mountain that juts out of the water in the middle of a seemingly endless ocean. The mountain has little more than a lighthouse on top of its peak, with a peroulis road leading up to it. It is estimated that the mountain could be as high as Olympus Mons. Curiously, there is no snow on top, the climate is stable, and the air is fine to breathe. However, the winds are unbearable, blowing over everything that attempts to climb it with tornadic winds exceeding 2500 kph (1553 mph) . It is unknown how the lighthouse stays in place.
Attempts to Climb
The first attempt to climb the mountain by the M.E.G reached about halfway before being forced to turn around due to the increasing wind speed.
The second attempt to climb, also by the M.E.G, ended up with much the same fate, although they did manage to take this photo to the left from about 10 miles up.
The third attempt to climb, by the Backroom Colonists, made it about a quarter of the way up before deciding to set up an outpost closer to the base of the mountain

The fourth attempt, once again by M.E.G made it around 15 miles up, nearly 2/3 of the way to the peak using advanced climbing and wind gear.
A fifth attempt to climb is currently being planned by the M.E.G
Level 520.2
One of the many holes in Level 520.2
Level 520.2 is the endless ocean that surrounds the mountain. The ocean floor is riddled with holes and ledges that go on as far as the eye can see. There have been several missions to try and find the bottom of these holes, none of which have succeeded.
The sea is usually warm, and it has been confirmed to be salty. During the day, the water is usually calm with few surf-sized waves. But at night, a storm engulfs the whole sea and island and it begins raining like a hurricane. The waves swell to huge sizes and crash over the rocky shore. Some people even report strange growling noises coming from the holes during this stormy period.
Entities
This level is mostly devoid of entities, with very few rummaging about. However, some speculate that there might be a great monster below the waves.
