The new thing teased yesterday by Playerunknown's Battlegrounds creator Brendan Greene has been unveiled as Training Mode, which as the name suggests will give players an opportunity to learn and master the game's mechanics without the risk of being murdered if they stick their head up.   

Training Mode will support 5-20 players on a new 2x2 km map with facilities that cover all aspects of the game: There's a shooting range, as Joe speculated, plus practice areas for parachuting, melee, parkour, and "throwables," multiple racetracks, an indoor CQC range, and more. The idea is to offer something for everyone: Newcomers can get a handle on the basics without being shot at, while dedicated players can familiarize themselves with more advanced features like weapon attachments, recoil, and bullet drop.
