Update: Activision's posted the official trailer, confirming Destructoid's leak. The new Spacey-based shooter is Call of Duty: Advanced Warfare, and it's out on November 4, 2014.
Earlier today, Destructoid said it learned through a "trusted source" the game centers on a mercenary group led by Kevin Spacey's character, and this renegade faction has the US government in its sights. That tallied with what Activision's teased, and the publisher's now released an official video ahead of the expected reveal on Sunday, May 4.
The trailer showcases futuristic elements like soldiers clad in beefy-looking exoskeletons, and a whole bunch of hover-things including hover-bikes(!). We'll keep you updated on further details as they trickle out.
