Fortnite's Battle Royale mode continues to grow into its own game basically, as Epic launches patch 1.11 and heads into Season 2 and the new winter event.
This new season will bring the "Battle Pass" concept with it, which includes cosmetic items with an instant unlock, and an additional "level-up" system that grants more loot. Season 2 will run through February 20. Other optimizations are in tow like framerate enhancements, as well as bug fixes and some other minor balance changes.
What amazes me is Epic's open development process, which has quickly stamped out balance problems or bugs in a matter of days after the community has reported them.
