I was running towards a downed chopper. That was outside Airfield. I don't really remember the exact location on the airfield since I'm still pretty new to the game. I'm just upset because I had a ghille suit that I never put on my guy, cause when I started falling a zombie started hitting me and there was no way for me to defend myself.
If anything a way to get it back or as it was time consuming to fine all that was needed for it.
