A new campaign trailer for the upcoming Gears of War 3 has been revealed which gives us a very brief new insight into the story as well as showing off lots of nice explosions and shooting action. The trailer is set nicely to Black Sabbath’s “War Pigs” which is nice and everything but I don’t see it taking off as well as their infamous “Mad World” trailer for the first game. Check out the brief teaser after the break, and get ready to finish the fight. No other game has used that tagline have they? Epic should use it for Gears of War 3, it sounds cool.
