Since its early access launch in December, the Xbox One version of PlayerUnknown's Battlegrounds has featured only a single map. The second map, the desert-themed Miramar, will finally make its debut on console this week, but only as part of a limited-time test.

As for the PC version, a third map, Codename: Savage, is in the process of being tested, also during limited-time windows. Some new areas were added to that map, and underground caves are also on the way. Meanwhile, PUBG Mobile just got a big update.
