EA just released the first trailer for Army of Two: The Devil's Cartel. This is the third Army of Two game and is being developed over at Visceral Games (Dead Space 2 and 3). Salem and Rios are now out of the spotlight, and introduces two new characters running the show.
With the game running on DICE's Frostbite 2 engine, a new feature called "Overkill mode" lets the player do massive destruction to your enemies for a limited time. which makes sense to why everything was blowing up left and right in this trailer.
Army of Two: Devil's Cartel is planned for a march 2013 release for Playstation 3 and Xbox 360.
