Gearbox has previously hinted there was more Borderlands 3 stuff in the works, and now they’ve gone ahead and officially announced a second season of new content. It seems Season 2 will consist of two major updates – the Designer’s Cut and the Director’s Cut. We don’t know much about the Director’s Cut yet, but the Designer’s Cut will include a new skill tree for each Vault Hunter and a mode called Arms Race. Gearbox will be revealing more about the Designer’s Cut via a series of livestreams:

Gearbox already revealed a few details about Borderlands 3’s Arms Race mode earlier this month. According to Randy Pitchford, the mode will be “interesting” to those who enjoy battle royale games, but it won’t actually be a battle royale game. All we know so far is that the mode will take place on a standalone map, and there will be a heavy emphasis on the game’s guns.
