J.J. Abram's Star Trek Reboot in 2009 featured plenty of rousing action, but it was the characters more than anything that pulled us in. We cheered for the cocky, young Captain Kirk and the uptight, sombre Spock. The former full of talent but lacking in guidance, and the latter conflicted between his buried emotions and ultra logical upbringing.
Digital Extremes (The Darkness 2, Dark Sector) seeks to capture these strong personalities through its "asymmetric co-op." You play as Kirk and Spock as the pair explore strange new worlds, seek out new life and new civilizations, and boldly go where no man has gone before.
Both characters have special abilities that correspond to their unique characteristics. Spock can mind meld, perform the Vulcan death grip and use his tricorder to scan for enemy weak points, while Kirk can exploit said weak points and call the Enterprise down for an aerial assault.
