If you want to see the future of PlayerUnknown's Battlegrounds, the PC test server is where to play. Developer PUBG Corp. deploys frequent updates to the server to beta-test new features, and a new patch was released today on Steam. In addition to tweaks to the desert map, the patch also adds a new anti-cheating measure.

The desert map, called Miramar, has been playable for around a month now, and it's provided players a significantly different experience to the original map. Although it's largely been received positively, the studio has received some feedback, and this test server update attempts to address certain complaints. For example, the patch adds more structures and cover "to improve the engagement experience," adds more off-road routes, and rebalances the item spawn level of certain areas.
