Laying traps in PUBG can be difficult as most players are well aware when things are too good to be true. Turn a corner and run into a room full of weapons and meds, most likely a trap. Drive around and see an abandoned warehouse with first aids everywhere, it's probably a trap.
That's why it's all about presentation. You can't go crazy with the bait. Maybe lay one weapon down with some ammo or a few med kits. But the question is where can you wait to kill the enemy.
Redditor Nitesen posted the clip on PUBG subreddit, and shows how to lay the perfect trap. Laying a couple gas cans in an open warehouse where they normally spawn, he then proceeds to place two med kits nearby. Players will go for the med kits not paying attention the gas cans.
That's when he strikes. While some people will complain about camping, it's a big part of PUBG. And if we get more hilarious clips like this, I'm all for it.
My advice is to avoid a cluster of gas cans, even if they look like they normally spawned, as you never know who is watching.
