A full-blown trailer for GI Joe: Operation Blackout was released today. Screenshots and footage have been leaked before, but this is the first official look at the game.
The game looks to be a third-person shooter where you can play as both Joes and as Cobra. Duke, Snake-Eyes, Scarlett, Roadblock, Cobra Commander, Destro, Baroness, and Lady Jaye are shown as playable characters.
