I've been playing for the past couple weeks because my kids have finally gotten into it. The kids are 16 and not quite 13. I've been having a lot of fun with it playing the zero build mode. I tried it way back when, but didn't really get into it, but I don't really remember why. I loved PUBG, though I was terrible at it, and this is basically PUBG lite an dI a way less terrible at it.
The key stuff I have learned over the past couple weeks is to basically go for 3 weapons, close range, mid range and long range. For me I prefer a shotgun, pretty much any one will do) for close range, a Hammer assault, but I will take any other, for mid range and a DMR for long range. Heavy sniper is nice but reload time is a killer.
For the other two slots, generally healing (med mist preferably) and shields (Chug Splash or shield keg). If you are being more aggressive and can use them effectively, boogie bombs are fun. Rift to go is a great escape option and the port a fort is another handy tool. The challenge is that you have 5 slots and want to carry so much more.
The best players bounce like a freaking ummm... what bounces a lot? and still have great accuracy. You have to keep moving or you are just target practice.
Unless your team is really coordinated, solo is probably easier. Letting others start fighting each other and you finishing it is even better.
Of course I am rarely the winner, do take all that I've said with a salt lick or two.
