Here's an answer : The film viewer feels incomplete and has many bugs. You may
see one thing in the film, however inside the game it may have happened differently.
Read as : Press fire all button in game, all guns with a line of site will fire, but not ALL guns will.
In film, it may see the 'fire all' input, and fire ALL regardless of which actually fired.
No, not every single gun is supposed to fire in one or every single direction. You really needed
to open a forum to discuss that? I think you lost your common sense at that ridiculous altitude.
