Do not leave this bush.
If you leave this bush you will die.

this will be boring, half an hour may pass with nothing happening. this means you are playing PUBG correctly.
Do not leave the bush. You will die to some BS autistic camper using cheats if you do anything.

To pass the time I recommend opening youtube videos in the steam overlay. Make sure the audio is less than PUBG so you can hear the unlikely footsteps of someone finding your bush.

Podcasts are recommended unless you're the kind of person who can quite happily zone out to music for an hour.

You may also use this time to catch up on any literature you've been putting on the back burner, or any studying you might need to do.

Heck you could probably just alt-tab out of the game entirely and do something else,
with a recurring timer set on your phone to check every 5 minutes whether you're still in the safe zone.

as I said, this is the correct way to play PUBG as doing anything will get you killed.



make sure your bush is inside the circle.
if it is not, you will have to find another bush to sit in within the circle.

I have won games by setting a timer as mentioned before as well as using google chrome desktop with my phone to check on my within death circle status while going downstairs to watch netflix and grab some pizza.

you may have to kill one guy at the end, but up until then the correct strategy is to allow everyone else to kill each other.
Why put yourself at risk?
