To the Swords from the launch trailer..the duel wield pistols..the open world game play..the mission in an early class video where the op used disguise got behind enemy lines to interrogate some one..look at some of the brink videos from just a few months ago...we did not get what they advertised at all ..lol
That's a trailer nothing more.... A while ago we had a thread of all the things you can't do based off the trailer. This was made in about December and we had a huge list. Including but not limited to, back flips, distracting people with your hand when they are looking through a scope, and customizing your grenades with the words "Sick em with the thunder."
Trailers are to get you to drool over the game not to show off in game footage.
