PlayerUnknown's Battlegrounds launched its Event Pass progression and reward system last week, in concert with its new Sanhok map. After several days of feedback, developer PUBG Corp has adjusted its workings to better suit players. For now, these changes apply only to test servers.

The changes see the Event Pass' daily XP limit increased from 80 to 120, while the minimum play time that counts towards missions progress has been reduced from five minutes to two minutes. Likewise, the minimum time required to acquire XP has been halved—down from five minutes to two and a half minutes.
