So they came out with a free to play version of PUBG that runs on shitty computers called PUBG lite. It looks to me to be a port of the mobile game, but I don't know what I'm talking about. It has the same stuff as PUBG but also a 4 on 4 deathmatch, which looks like fun for the gunplay. I don't think it's on any game service platforms, you just download it from the website.
