Make a decision where you want to land before the match starts, have a few different places in mind and then as soon as you can make it, jump and get to the ground as quickly as possible. The faster you get to the ground the faster you can get a weapon. Do not screw around with your wing suit or you will land and struggle to find a weapon before another player finds you.
My first couple of matches, I would get a weapon and stick with that for as long as possible, sometimes hiding and waiting for others to come my way. I did not have much success at all with this. I would advise that you always keep moving and looking for something better than what you have. This keeps you on your toes and ready for any guys who are trying to take you down.
The perks that you can get in Blackout mode are awesome and do not do what I did at first and that was waiting for the “perfect time” to use them. The perfect time may never come and you sure as hell cannot use them when you are dead. I use any perk or consumable as soon as I get it.
The best advice I can give you is to just keep playing. You will get better each time, figure out new strategies, learn the map better and best of all you will have a lot of fun while you play.
