The funding also has stretch goals; the more funds are raised during this period, the more costumes will be unlocked after funding is completed on July 19th. So purchasing the Heart of the Golden Lotus pack gets you some costumes now and the promise of more costumes once everything is said and done. There are even more milestone costumes if funding manages to exceed its target; it’s currently sitting at 26% funded, so you’re invited to make your own predictions about how high it’ll go.
