This Map is the spiritual succesor of Calcium City, with many awaited Features/Bugfixes.

  • You spawn in an airplane, use the included glider to safely glide to the surface.

  • Please only jump out the airplane once you see ground beneath you, otherwise you could die. Error Text here if it doesn't work

  • Here is an example of landing with the glider, i'll explain the controls later in the description. Error Text here if it doesn't work

  • This is me practicing some shooting after i landed. Error Text here if it doesn't work

Thanks to these guys!!!

  • AlexTheBaba for providing the glider and helping me out with terrain.
  • zCubed for the foliage shader used on trees and other helpful stuff.
  • Ethi also for terrain and material tips.
  • Skyline_Robot for the PM since i used it in the clips.
  • The BW Community for feedback and helping test the map :D


  1. The Map's file size is currently roughly 400 mb.

  2. Better overall lighting and reflections.

  3. A vast landscape with soon coming secrets and unique locations.

  4. Better Performance, yes this even runs on a potato pc.

Enjoy!! Hope this is a good succesor towards the original Calcium City.


  • Soon there will be traffic with several modes...
  • Soon there will be night mode...
