It's even bigger now. The central condo you have all already seen. I am also in the process of adding four additional "satellite condos". This will allow the map to be utilized in the upcoming community condos system. For example, Players can have their own homes in the smaller satellite condos, and everyone can have a shared community center in the central condo. Or, if you are alone, it just means you have a lot more floor space, and a lot more to explore in general.
All five of the structures are accessible in two ways. The first way is to go on a walk on the ocean floor from one condo to another. Each condo structure has an airlock to get in and out of the condos, and you can freely explore the ocean floor. Additionally, there are islands of hexagonal shaped panels on the ocean surface. There exists a building platform like this on the surface above each of the five structures, connected by bridges. Each platform has its own elevator that descends into its associated condo.
