During Heart Month this February, Fortnite players around the world will step into a powerful, story-driven experience that blends gameplay, empathy and real-world impact. “Super Pet World,” a free-to-play Fortnite island developed by Ghost Gaming, is launching a limited-time side quest, “Side Quest: Heartbeat on the Wind,” created in support of Enduring Hearts, the only nonprofit organization dedicated exclusively to funding pediatric heart transplant research.
