PlayerUnknown’s Battlegrounds will get a special three-day event starting later tonight, and the theme seems to be togetherness. The mode is called “Tequila Sunrise,” and it will only spawn shotguns and melee weapons on Miramar. No other weapons, no other maps.

Find some friends, because this event mode is for four-person squads.
