This is a pre-release internal note from the closed playtest, quoted as it was written for testers. It describes a build that no longer exists; treat it as history, not as a description of the current game.

Another Thursday, another Byrdlett patch! This one brings a brand new Act 3 boss and a whole host of balance and UX changes. Many changes have been made to multiplayer specifically, so be sure to try out a multiplayer run if you haven't in a while! Also, the art additions that didn't make it into last week's patch have now actually been added.
