PlayerUnknown's Battlegrounds' tropical map, Sanhok, is returning for one more stint on the Experimental Test Server before it finally launches. The next Sanhok test takes place this weekend, and as before, it's available to everyone who owns PUBG on PC.

Developer PUBG Corp. announced the new round of testing in a post on Steam and said the upcoming beta will likely be the final one it holds before it implements Sanhok in the live game. "If everything goes according to schedule, Sanhok will come to live servers near the end of June," the studio wrote.
