To celebrate the day, Epic is dropping cake, bringing back Playground mode tomorrow, adding a new weapon, and rolling out a themed quest. Plus, llamas.
“Celebrate #Fortnite1st with cake, loot, and a special in-game questline. Complete the questline to unlock Birthday Brigade Ramirez. While you’re partying, find and eat birthday cakes to earn event tickets which can be spent on the limited time Birthday Llama.”
The non-birthday stuff in the patch is worth a look took; Epic has basically made building easier and damage to structures more potent, running is less annoying, the kart got a nerf, and the resurrected Playground mode has new options to “let you and your squad set up team battles for practice and training.”
