In May 2014, the official Call of Duty website was updated with a scrambled image that was due to be revealed on May 4, 2014. However, the trailer was leaked ahead of schedule on May 1 and then officially released soon after. The trailer revealed actor Kevin Spacey as portraying a character in the game who resents democracy.[7] The trailer contained a variety of futuristic technologies, including cloaking aircraft, twin-rotor drones, hover bikes, "spider" tanks, specialized weapons, powered exoskeletons, scan-tron grenades and gloves that allow their wearer to climb up walls.
