Fortnite: Battle Royale may have caught some flak from the makers of PlayerUnknown's Battlegrounds, but that didn't stop it from becoming an instant hit. To build on that success (and steal some of PUBG's thunder, ahead of its arrival on Xbox One), the free-to-play title is adding an insane new game mode. Instead of a 100 player free-for-all, it will be two squads of 50 scrapping it out till one team is left standing. The free mode is available until December 17th on PS4, Xbox One, PC, and Mac.
