What this mod does, it improves the sceneries of all 34 landing challenges. Some mild and some heavy improvements have been made; even the ones already enhanced by Asobo, have been improved.
You can download the demo with the first 12 Challenges (all famous ones) on Flightsim.
Needless to say, the enhanced sceneries will be there even if you don't do the challenges.
Please refer to the README file for additional information.
IMPORTANT: you need to have all 4 world updates installed.
