While many players will instinctively play carefully, avoiding conflicts and sneaking around (especially while still learning the ropes), if you want to get better at the game, you might be better off taking a more aggressive stance. When you air-drop in bigger cities and larger settlements, try to hunt down other players, and spend time driving around the island, you will get killed more often — but you’ll also learn a lot more.
A big part of PUBG is knowing things like when and where you’re vulnerable, what weapons are most formidable in which situation (you can compare their stats on the game’s wiki), where you can expect to find vehicles or high-level weapons, and where players are likely to congregate. The only way to really get good at the game is to experience it. Hiding out in a few small, scattered buildings might let you get to the Top 10, but it won’t teach you how to win when you arrive. While you might be a more cautious player by nature, it’s worth getting yourself killed a few times to learn more about how other people play the game, rather than surviving through several uneventful matches without learning anything.
Consider death to be your teacher in PUBG. You’ll go through matches quicker, but you’ll get a better sense of how to handle yourself in a fight and what to look out for. In the end, you’ll waste less time. PUBG offers no post-death information like a kill cam (although according to PlayerUnknown at E3 2017, it’s coming to the game in a future update), so getting sniped from some unseen foe teaches you nothing that makes you better. Learn by doing instead. You’ll appreciate the skills you build for later matches when you’re better equipped to sneak around and outsmart players.
