I think I remember it saying it one a film festival award in description
Plot was three friends are hanging out in this wooded area. One of the friends gets his head blown off my a random sniper. Eventually one other of the friends gets sniped too. The last surviving friend finds an abandoned factory where the shooters (I think there were two shooters together) were and kills them.
The movie had a homemade quality to it
I have no idea what the name is and can’t find it by searching on Google.
