You stand alone atop the throat of the world, the once proud home of the greybeards (or whatever they're called) in fiery ruins. Alduin circles the air above, you raise your shield and ready your blade, alduin dives toward you fire scorching from his gaping maw. The game fades to black then redirects you to the gamesas site telling you that the DLC 'Final battle with Alduin' will be available for purchse in 6 months.
You scream.
You scream.
One day, a developer is seriously going to try this. I just know it. D:
