Borderlands 3 Echocast is an extension for Twitch that allows you to link your Borderlands and Twitch channel in order to get free loot while watching Borderlands 3 streamers. This kind of interaction between playing and watching a game is unparalleled, but the main thing you need to know is that if you watch a lot of Borderlands streamers then this will help you grind gear when you’re not able to put time into playing the game itself.
In addition to this, you’ll also be able to use the Borderlands 3 ECHOcast extension to browse a streamer’s gear, abilities, and more. That means you don’t need to ask the streamer for details on what they’re using or what weapons they have access to, so everybody wins.
However, while it’s fairly easy to get the ECHOcast extension working to the point where you can look at your favourite streamer’s build, there are a couple of extra things you need to do in order to claim loot from rare loot chest events.
