Epic Games have announced the next Fortnite update, v11.11. The new Fortnite update will be available tomorrow.
Update: The v11.11 update has been delayed. No new date has been provided.
Finally some communication from Epic Games. Last week, Epic added the Harpoon Gun to Fortnite Battle Royale in the v11.10 content update. There was no announcement through the MOTD that a new weapon would be added to the game, nor was there the usual announcement letting players know there’s an upcoming update.
Epic have posted on the official Fortnite Twitter account that the next update will be the v11.11 Fortnite update. The update arrives tomorrow, November 12th, and downtime for the update will begin at 4 AM ET (8 AM UTC).

In the tweet, Epic announced that the patch includes new content for Save the World as well as addressing some known issues in all the Fortnite game modes, including Battle Royale.

It’s still possible Battle Royale will see a new item added, but with Epic deciding to take a back seat when it comes to adding new content this season, we wouldn’t be surprised if Epic decide not to add anything this week with v11.20 scheduled to release next week.
There’s a chance we could see some Fortnite leaks from the update, as we’ve not had new cosmetics leaked in a couple of weeks. If there are any leaks, we’ll be sure to post them out as soon as possible.

Update: Epic have tweeted stating the update has been delayed.
