Despite still being in early access, PlayerUnknown's Battlegrounds is already one of the biggest gaming success stories of 2017. It's one of the titles featured as part of last month's Twitch Prime promotion, and canny players have found that it's possible to make a little bit of cash from the in-game items being offered.

For those unfamiliar with Twitch Prime, it's an added benefit to an Amazon Prime subscription that was introduced when the retail giant bought out Twitch in 2014. Members typically get some freebies every month, ranging from in-game items to fully fledged games.

Last month, one of the bonuses being offered up was the PlayerUnknown's Battlegrounds' Twitch Prime set, which is an in-game costume featuring an exclusive t-shirt, jeans, and balaclava. Cosmetic items for multiplayer games are frequently very popular, but there's a huge amount of demand for this particular set.

Steam has long since allowed users to buy and sell this kind of content on its Market. At present, the Twitch Prime set for PlayerUnknown's Battlegrounds is routinely selling for over $20, with some listings going for almost $30 — a decent profit, given that the items were being offered up for free.

Of course, there are a few caveats; players needed to have an active Amazon Prime subscription, have that account linked to their Twitch profile, and they also needed to own PlayerUnknown's Battlegrounds. Anyone that happened to redeem their bonus but not use the item for themselves could stand to make a few bucks by selling them now.

It remains to be seen whether a flood of users adding their Twitch Sets to the Market will cause prices to crash, or whether users who hold off will be able to sell the items at an even higher price further down the line. Whatever the case may be, limited-run in-game items certainly look set to be a lucrative revenue stream for PlayerUnknown's Battlegrounds going forward.

PlayerUnknown's Battlegrounds is available now for PC, with PlayStation 4 and Xbox One versions currently in development.
