In 2017, Mixer launched a channel for PlayerUnknown's Battlegrounds that leverages Microsoft's HypeZone technology. The artificial intelligence-powered system works to scour select games for crucial moments and help viewers find streamers of potential interest to them during those highlights of the game.
Mixer expanded HypeZone to Fortnite: Battle Royale early last year, and now it will be using the same technology for its new rewards program called Mixer Loot. HypeZone will work to scan for streams that may contain key moments and surface them to viewers. If you happen to watch a particular game that supports Mixer Loot, you can earn in-game content.
However, Mixer Loot won't be available on all channels. To determine whether a particular channel is Loot-supported, simply look for the program's icon beside the stream's title.
The rewards program will be rolling out from April 30 in time for the release of Sea of Thieves’ Anniversary Update, which will bring with it a whole bunch of new content and features like fresh story quests, Arena, and more. You can earn the game's Obsidian Six Item Pack by just watching 30 Sea of Thieves Arena matches on Mixer in full from April 30 (8 a.m. PST) to May 5 (11:59 p.m. PST).
You can check the rewards you've accumulated by clicking the Loot icon on the stream page and heading over to the “My Loot” page in the settings page. Also, loots are redeemable on any gaming platform. It should be pointed out as well that the program is limited to only a single reward code per account per unique Loot opportunity.
