Getting a crate in PlayerUnknown’s Battlegrounds is meant to be a reward for the player, but it’s also frequently meant something to resell on the marketplace. However, that’s been rather more impossible with the newest crate, which was added to the game on May 13th and still hasn’t been unlocked for the Steam Marketplace. The developers have announced that it will be available to sell on the Marketplace on June 13th, making it nearly a full month between implementation and resale.
If that bugs you, you’ll be unhappy to know that it’s going to be the norm at this point; the announcement states that keeping longer lockout times for the marketplace will help curb abusive behavior in and around the game. Whether this will help actually alleviate issues or just drive up certain rare and desirable item prices is, of course, an exercise in speculation best left for the future.
