Join your friends in Tiny Tina's Wonderlands by enabling crossplay

[Windows Central]

Party up with your friends no matter what platform you're playing on.
While crossplay wasn't available in Borderlands 3 at launch, it will be in Tiny Tina's Wonderlands. Even better, crossplay in Tiny Tina's Wonderlands will be enabled across all platforms, allowing those on Xbox, PlayStation, and PC to play together. Enabling crossplay in Wonderlands is fairly simple because of an opt-in window that everyone will be greeted with, but actually trying to join up with your friends may be a bit more difficult if you don't know what to do.
