H1Z1: Battle Royale has left open beta and officially launched as a free-to-play title on PlayStation 4.

The premise of H1Z1: Battle Royale is essentially the same as all battle royale titles - be the last person standing. This means making use of abandoned vehicles, coveted airdrops, and avoiding the creeping toxic gas while completing challenges to earn in-game currency. This currency can then be used to buy new skins for vehicles, weapons, equipment, and clothes.
