Well obviously it is based in the near to far future because they are in space. And I'm not sure, but that big thing in the middle looks somewhat like a robotic torso and head. Like a robot's upper body. Which I would guess is the bad guy of the game. And if he's hovering above Earth, I can only guess he plans to rule it.
That's all I got.
Or that may not be a robot, and that could just be a picture of a space ship taken from outside the hull.
