Within the decaying grounds of Starr Park, an amusement destination left to rot since a disaster in 1995, a bizarre transformation has taken root. The discovery of strange purple gems scattered throughout the abandoned park bestowed immortality upon those trapped inside, but the gems' chaotic influence extended far beyond preserving life—they warped the environment itself, animating lifeless structures and distorting the local wildlife and vegetation into unnatural forms. The survivors, now wielding superhuman abilities as a result of their exposure, remain locked in endless combat across the park's crumbling attractions, their transformed nature binding them to this forsaken place.
