Earlier this week, PUBG Corp. announced the latest cosmetic unlock system for PlayerUnknown’s Battlegrounds: the Event Pass. The pass is designed to help commemorate the launch of Sanhok, the game’s third map, and is supposed to reward players with certain cosmetic items for completing challenges. Players will be able to purchase the pass for around $10 once Sanhok releases officially on June 22. While we don’t know exactly what the challenges are yet, we do have some idea of the rewards.

The Event Pass itself has 30 levels of unlocks and around 24 cosmetic items — the other levels grant you things like XP or extra BP — which range from jackets and pants, to prison jumpsuits and police uniforms. Of these items, 17 will be unlocked permanently for your account if you reach the required level, while seven of the items will only be unlocked temporarily. These items are cosmetics that have already been available in PUBG through previous crates, but players who unlock them will get a “temporary trial” with them, which will likely last as long as the Event Pass does.
