GayaSimulation, a developer group behind sceneries such as Courchevel or Vienna Airport, has a few weeks ago given the opportunity to the flight sim community to claim a free copy of their upcoming Kos (LGKO) scenery for both Prepar3D and X-Plane 11, and since then has been updating us on the development status by sharing new previews.
GayaSimulation today posted a new set of previews on their Facebook page showcasing the airport area, night lighting, and the island of Kastri.
The developers also mentioned in the comment section, that P3D previews are coming soon. The release date is still unknown.
