Fortnite's recent Teams of 20 mode has come to an end, but players won't have to wait long to jump into the next limited-time event for Battle Royale. Epic has revealed that the next special mode coming to the popular free-to-play game will be Blitz, and it kicks off on PS4, Xbox One, and PC early next week.

As previously detailed, Blitz mode features much shorter match times than usual, which Epic says results in "faster [and] more intense matches." The maximum duration of a match in Blitz mode is 15 minutes, and each one begins with the storm circle already closing in.
