It is shortened drastically. The "real in game footage" answers the question for all those asking "is this just a promo movie?" The sound of the depth charges is nice in my opinion.
I do wish they kept the "peaceful" scenes in. More interior shots, and the engine room.
I do wish people hear would understand that to market to the masses you must bow down to the next to lowest common denominator.
For most on this Forums hearing German dialog is just sauce for the goose. But for a person who has never tried a subsim, the German might be disconcerting. Which could affect sales.
In other words for posters here, please can the "terrible dialog" statements until the game is out.
I hope this re-release of this trailer means a new one is on its way out.
