It’s time for another event mode in PlayerUnknown’s Battlegrounds, and this time, the game is asking players to be a little stealthier than normal with the Ghillie Crossing mode.

Ghillie Crossing takes all guns and vehicles out of PUBG entirely, and replaces them with crossbows and melee weapons only. Alongside these weapons are regular items like grenades, health items and attachments, as well as ghillie suits, which, for the first time, will be a regular loot item in this mode.
