The process of getting crates in PlayerUnknown’s Battlegrounds is not necessarily all that rewarding. You pay your hard-earned BP to get a crate, and it may randomly be a locked crate, requiring a separate purchase of a key. There’s also a feeling of not getting much out of the crates whether they are or aren’t unlocked. So the upcoming changes to crates are designed to address those problems, starting with the removal of locked crates from the drop tables altogether; keys can still be purchased only by players who retain locked crates in their inventories.
This goes hand-in-hand with adjusting the drop rates for items to make opening crates still feel valuable and rewarding while keeping the rare rewards still unlikely to obtain. Players will most likely notice that weapon skins show up more often and are of an overall higher quality, but the overall rarity of high-tier items should be preserved. It’s a set of changes that will be rolled out in phases, with locked crates not gone altogether until December 18th, but we would imagine players will be happy that the change is happening at all.
