Following its recent flares and shotgun/melee custom bouts, PUBG's latest limited-time mode is named War. Billed as its "most deadly Event Mode yet", the ten-person, squad-based deathmatch free-for-all is live now through Sunday, April 15 at 7pm PST/Monday, April 16 at 3am BST. 

Set within a "small slice" of the Erangel map, games last 15 minutes and host a maximum of 30 players in ten-person teams. Unlike the familiar battle royale formula, dead players respawn in a plane before being dropped back into action—and kills earn points for each respective team.
