Mattastic submitted an updated alpha version of his first terrain for Arma 3, Alaska 2035, which he previously released on the BI forums.

Welcome to Alaska. It's 2035 and eastern aggression has brought war to the wild frontier of Alaska. Working within the constraints of Arma 3 vanilla content, I am working to bring a representation of a war time Alaska to life. The terrain is at a point where I can release the alpha version. Please feel free to post your comments, questions, and complaints about the terrain. Keep in mind that there is still A LOT of work to be done, and is by no means a finished project. However, the terrain does have some areas that could definitely be played on.

Changelog:
• Updated Satellite image
  
• Removed tree outlines outside of townson sat image (Trying out new method).
  
• Filled in trees around airport
  
• Adjusted terrain in Beaver, Seldovia, and New Stuyahok
