It’s official: Fortnite is now one year old. And to celebrate the occasion, Epic’s epic battle royale shooter is getting a sizeable patch update – alongside a number of birthday challenges for the next... fortnight.

Each challenge completed will reward players with different birthday-themed cosmetic items or XP boosts, while completing all three will give you the chic Birthday Cake Back Bling to wear with pride throughout the two-week celebration.
