"Halo 4: I Get a Woman!" - Sgt. Mjr. A.J. Johnson, RIP

Considering a large portion of the Halo 4 marketing with that giant black ball bearing which flies around, it does have some semblance of the movie "The Prisoner", thus the picture was not out of context at all.
May want to check up on your sources before calling things out of context.

First, Halo Wars has great music and a great score. Not just from my opinion, but considering it's a technically well-built score in general. It's not the same as the FPS' scores, but who cares? It's still a good score and it's telling a different story being told by different narrators in the same universe. That same concept can be applied here. It's a new trilogy with new narrators in the same universe. It's a smart marketing move if they want to use dubstep since it is a popular musical style. We have heard Halo 4 only having inspirations of dubstep in the actual game, as evident in that trailer's legitimate gameplay footage and other videos that are not trailers.

Second, The Prisoner is NOT Halo 4. That picture is out of context because it does not supply the rest of the story and why that sphere is flying around in the first place. The Halo 4 Sphere is chasing the Infinity. Then the Chief chases after it. Does the sphere in The Prisoner chase after a massive spaceship for the same reasons? Does the protagonist then chase after that same sphere? My argument against that picture is that it does not supply proper context to accomplish your argument. You brought a knife to a gunfight and I want you to show me your gun (video of that scene).

We do not know if the Rover is the same as the Cryptum. We won't know until the game is out. However, according to the below sources and the video, the Rover was meant to keep people in The Village and the Cryptum was meant to hunt/chase down and destroy intruders perhaps.
