The proceeds from the new limited-time crates will fund the Gamescom PUBG Invitational prize pool.
There will be a PlayerUnknown's Battlegrounds esports tournament at this year's Gamescom, and the prize pool will be funded through limited-time microtransactions in the game. That prize pool will be $350,000, and will be awarded to the winners who score the best across three games. The Invitational will include Solo mode, Duo mode, Duo first-person mode and Squad mod, and will span four days.
The new microtransactions will take the form of a limited-time crate and key system that will launch on August 3. Three new crates will launch that day - the Wanderer Crate, the Survivor Crate, and the Gamescom invitational Crate - and they will be filled with cosmetics inspired by the Battle Royale movie. While the first two crates will be opened with Battle Points, just like the crates already in the game are, the Gamescom Invitational Crate will require a special key. That key will cost $2.50, and the proceeds from that crate will be used to fund the Invitational prize pool and the setup of the event.
You can find more information about the event, and who's playing, over on the official PUBG website.
