It has been less than two weeks since Epic added Duos and Supply Drops to Fortnite's Battle Royale game mode, and already they are planning an absolute ton of new features. You can expect the upcoming patches to bring team communication (including voice chat support), improvements to loot density and inventory management, an anti-cheat system and performance improvements, stats and leaderboards, a better progression system, and the list goes on.
There are far too many major additions to cover in brief, so if you're interested in all of the details you'll find the full list down below. Its a bit on the lengthy side, but there is very little padding, so if you're interested in Fortnite's future I'd say its well worth checking out regardless. Have a look:
