Use The Doors Smartly

Every building door in PUBG is usually closed. But you can use this to your advantage. When you enter the building to loot, close the doors to protect yourself against other players. If you keep them open, you won't hear them when they enter the building. Apart from protecting yourself, you can use this strategy to kill some unsuspecting enemies too.  Another instance to utilize closed doors is to slow down the enemies while you cover some distances. Players will assume that the building hasn't been looted and will waste time trying to ransack the place for goodies.
