Hey all,

Were extending Chapter 2 – Season 2 of Fortnite beyond the original April 30 date. Our plan is to launch Chapter 2 – Season 3 on June 4.

Before then, theres lots of content coming in the current Season. We have multiple game updates on the way that will deliver fresh gameplay, new Challenges, bonus XP, and a couple more surprises up our sleeve!
