Don't listen to any one of the previous repliers! They just want to find you and kill you when you think your safe!
Just kidding. They all shared some good intel. Except the land at an unnamed place/crappy place from
@Coyotekins_YouTB! That will actually get you killed faster XD. You know ppl who drop there? People like me who know that either ppl go there to not fight (noobs/loners/campers) or who just wanna explore. What do ppl like I do there? We come in packs cause we know we can gang up on those suckers. I'm joking here too. I don't drop at those spots but I do run towards those spots right after I got a gun.
My advice which nobody has said yet surprisingly is just run and spam the pickup button. Get fast at looking around and tapping that button.
Spawns usually happen in same places so instead of 'getting to know the map', get to know spawn locations. By that I mean a 3 story building you can loot has 4 walls and 3 stories (for simplisticity's sake), at which wall usually spawns the loot.
I've had matches where I didn't find weapons after I ran through like 5 buildings, so sometimes you just get unlucky...
Especially if you find the mozambique and suddenly there's an entire team in front of you with spitfires...
