Alongside the launch of the new Sanhok map, PUBG will be adding something called the Event Pass. This is similar to Fortnite's Battle Pass and allows players to earn various cosmetics by purchasing it and completing objectives. However, news of the Event Pass has proven to be controversial, angering many players who feel the game is still not in great shape. Seemingly in response to these frustrations, developer PUBG Corp. has announced plans to give away an additional pair of items to all players, Event Pass buyers or not.
