A teaser trailer named Mask of Mayhem is teasing something Borderlands related ahead of PAX East. Gearbox will have its livestream from PAX East tomorrow starting at 2PM EST. The teaser shows off characters from the series along with some new characters. The announcement for the long awaited Borderlands 3 could come tomorrow, or Gearbox could potentially be doing a battle royale title much like Apex Legends. In the trailer, there also appears to be a Shift Code for Borderlands in each frame. We won’t know officially until tomorrow but the trailer is below for viewing.
