Like other Battle Royale games out there, PUBG sections up the map into a Safe Zone, a Red Zone, and a life-zapping danger zone. The Safe Zone is marked by a blue line on the map that slowly constricts, bringing people into a smaller playing area over time. If you’re caught on the wrong side of this blue barrier, your health will gradually drain, and you don’t want it to drop to zero.
You’ll also want to keep an eye out for the Red Zones that appear on the map. Here artillery fire will bombard the ground, making survival reasonably unlikely. If caught in a Red Zone, sprint or drive your way out as quickly as possible. If that seems impossible, seek shelter in nearby buildings so you can wait until the bombardment passes.
For those fleeing the encroaching Safe Zone border, or Red Zone bombardments, keep in mind that vehicles make a lot of noise – so pick your escape route wisely!
