Area 51 went dark hours before the Grays began their invasion of Earth. The former United States Air Force facility is now a Gray base of operations for the entire northern hemisphere and an ideal target for Chronicle X. Under the cover of night, the heroes of CX will attempt to deal a vicious blow to the aliens’ logistics in North America. The Twilight at Area 51 mini expansion tasks the members of Chronicle X with assaulting a fortified Gray installation. It adds night ops gameplay, including new trackers to manage the heroes’ current range due to limited visibility. —description from the publisher
