PlayerUnknown's Battlegrounds is now officially out on PC, and after a few issues that caused servers to crash, the game is playable again. The game launched overnight, after many hours of server maintenance that took the game offline. Fortunately, there's a free reward waiting for players when they log in.

For the next few weeks, players will receive a free in-game Winner Winner Chicken Dinner t-shirt, which will be dropped into your inventory after logging in. The 1.0 release comes with a few improvements to the game's stability and balance, as well. Developer Bluehole said previous adjustments had reduced stability issues, but it is expecting "progressive improvements" that should make the game more reliable in the near future.
