Butterfinger has teamed up with Borderlands 4 to release a limited-edition Butterfinger ECHO Skin that you can get for free, or unlock via purchase. Unfortunately, it’s only available to players in the United States, though it’s possible that the code that comes from it will be usable for anyone. We don’t know at this point, but if we find out we’ll update this article accordingly. The tweets that reveal the drop also don’t say when the giveaway ends, but it’s likely through September 2025.There are two methods to unlock the Butterfinger ECHO Skin for Borderlands 4: the first is to try your luck on their website and the other is to buy the Butterfinger x Madrinas Cold Brew Coffee Collector’s Box via GameStop or the Madrinas website.
