3. Watch Out For Black Smoke To Pinpoint A Supply Drop
A tiny point, but one that can save your life if you're caught without adequate ammo or weapons - be on the lookout for plumes of black smoke emerging from behind mountaintops or ravines.
These denote a past Supply Drop that's still "cooling off", and providing all the gear hasn't been snapped up, you can hop across and find better weapons, consumables or shields.
The double-edged sword of Supply Drops comes from knowing many other players in the vicinity will be on their way too, but get there first and you'll be far better off.
