How do I play PUBG for free?

Alright people have missed out a few key points:

1: You CAN ACTUALLY gift on steam but that’s not free

2:While PUBG mobile is a good alternative it’s a bit clunky and if used on an emulator it needs a reasonably strong PC

and your solution:

3: Get someone on your steam friends list to do family sharing with you and share PUBG with you. If you get someone who isn’t online a lot or is online when you are not, then you can play “their” copy of PUBG, However the 2 of you can’t be online at the same time, preferably find someone who bought PUBG and doesn’t like it so he doesn’t play it and you pretty much get infinite uninterrupted free play.
