This game is pretty much based on The Hunger Games, rounds last 20-25 minutes and your only objective is to survive and kill everybody else, as the round gets closer to the end 'poison fog' moves closer to the center of the map forcing everyone to run towards eachother and fight, you can craft weapons whilst running around or buy them by using 'FUNC' points which you can gain by either selling stuff you have found and some sort of machine, or killing other players, you can find containers or call in air drops to spend the points and perhaps get an awesome game winning weapon.
Right now there isn't really anything to it other than killing, there's no ranks and no achievements system in place.
Bought it today and have only played 2 games as of now, I killed 3 people in my first round and then suicided because I had to go AFK, it is great fun.
