Very large, very epic map. The environment is well thought out and constructed to feel like a natural mountain pass/forest. Great job on that. There's some cool secrets and interesting spots if you explore the map a bit. Very much a sniper's haven kinda map.

A few things to maybe consider:
-Walking through the forest, you can kinda get stuck on some of the trees. Maybe reduce the amount of solid brush trees and make them no colide with a keyframe can be an option. Or replacing them with meshes could work.
-When you spawn you're kinda out in the open at times and far away from weapons and resources. Try making those more abundant or reposition spawns.
-Adding more buildings or even cave systems can give players more escape options and cover from sniper spam.
-More lighting can definitely enhance the atmosphere of the map. You could add some natural lighting from the skybox or artificial lighting from other sources. (torches, floodlights, campfires, etc.)
-Lastly like what dvl_iac mentioned, go into level properties and give the map a name and author so it's easier to find on the map list

Overall great work sebastian91b!
