Very great opening, loved the music choice, even though it ended oddly for the teaser (Yes, I know you spliced it.)
There is some room for improvement. For example, someone who never played the game wouldn't know what the heck is happening with the switch from different views with the use of "Snap" view. So perhaps instead of using F7 or Snap view, try using F8 or Pan view. And since you had icons enabled in the film, F8 and Padlock go bullet-in-chamber with one another. To use it, simply press the "Tab" key on your keyboard until the aircraft's icon is selected. Then with the use of F8 (pan) the camera will center on the plane from whichever view you're using (Cockpit, external, or chase.) I would however suggest that you don't constantly use it, it would simply make some, "juicy," shots.
It might also help if you get in contact with Bnasty or other film makers to see if they will let you use some of their sound effects. The sound effects greatly increase the immersion factor when it comes to firing the guns, taking damage, and pieces of the plane ripping apart. And to add to the icing, film quality! Your film quality was not bad by any means. However again, you might get in contact with other film makers such as Bnasty or Niros to see what type of quality settings they use.
Very good for a teaser, I'd love to see the upcoming film.
