A new crate system in PlayerUnknown's Battlegrounds could make some extremely, extremely fortunate players a few grand richer.

Two new crates have been added to the game's test servers on PC, both of which have a 40 percent chance of showing up when you spend Battle Points on a crate. (Battle Points accrue automatically as you play the game, and are spent to receive a random crate type.)

"Biker" crates can be opened immediately, but "Desperado" crates require a key and – you guessed it – keys cost real-world money (US$2.50 each to be precise).

Throw in PUBG's new limit of six crate purchases a week, and it's easy to see how rare items from the game will be able to be sold on its Steam Marketplace for a pretty penny.

PUBG Corp. has kindly published the drop rates for the items within each crate, and as you can see, some items have a miniscule 0.01 percent chance of materialising.

Ars Technica crunched the numbers and reckons that on average, it will take a player buying the maximum of six crates a week 80 years to get an item with a 0.01 percent drop rate like the Sleeveless Biker Jacket. That's 10,000 crates. Woah.

For comparison's sake, 7.4 percent of all loot boxes in Overwatch contain one of the game's rarest Legendary items, a Legendary Hearthstone card appears in one of every 20 packs and golden Legendary cards appear about once every 230 packs, and it's thought that rare Exotic items in Destiny 2 appear roughly once in every eight to 10 boxes.

In related news, the same test server update has added a way to report cheaters via the PUBG replay function, so you no longer need to be killed by a suspected cheater to be able to use the in-game reporting tool.

"We encourage you to use the replay report tool as it is an effective and efficient way of making us aware of the players who are undermining your enjoyment of the game," said PUBG Corp.

Oh, and the game's energy drink no longer looks like a Red Bull can.

Over on the Xbox One version of the game, first-person perspective servers are now available in Duo and Squad mode in North America and Europe, but not Oceania.
