Mass Effect is traveling to a strange new world: California's Great America theme park. The Mass Effect attraction opens on May 18th at California's Great America in Santa Clara, featuring an interactive 3D presentation with 4D effects, all hosted by a live performer. Riders will travel to "a distant planet" to make a stand against "larger-than-life foes," though there's no word on which characters will make an appearance in the experience. The ride is made in conjunction with Mass Effect publisher EA, and developer BioWare announced it back in September.
