Update: A statement sent to GamesRadar+ by the Zynga communications team sheds some light on the nature of this apparent Borderlands Mobile shadow drop. The short version is that Gearbox was lightly involved in its development, this isn't a full release, and it's actually not even called Borderlands Mobile. Here's the company's statement in full:
"We are always exploring ways to introduce Borderlands to new audiences. Zynga’s NaturalMotion studio is currently conducting a limited-time test for an untitled Borderlands mobile project, with Gearbox providing creative guidance on the franchise’s design, history, and lore. We hope that players enjoy this new Borderlands experience and look forward to their feedback."
