How to Claim the Loot I Won from Watching Streamers Playing Borderlands 3 on Twitch
You can earn loot by being a viewer on a Streamer’s channel that is running the Twitch ECHOcast Extension. If the streamer opens a Red Chest while streaming it triggers a Rare Chest Event. As a viewer, you can choose to join the event and a random number of viewers will be selected as winners.
If you win you will then be able to choose one piece of loot from the chest that will appear in your in-game mailbox. You can find this by going to the pause screen while in gameplay and selecting Social. Then proceed to the Mail tab and claim your loot!
NOTE 1: You can only access the Mail tab while in active gameplay, not from the main menu.
NOTE 2: You must have your SHiFT account linked to your Twitch account and whatever service you’re playing the game on to claim your loot (Epic, PSN, Xbox Live).
