Just an heads up for those who do not look at the Steam front page too often.
Also worth a download for the original Battle Royale mod. Personal preference, I much prefer this to PUBG.
The Arma 3 engine does have its quirks for those not familiar with it but underneath, is a solid experience to be had.
To get the mode, install this along with the "required Items" and launch.
