We now have the full official trailer for Transformers: Age of Extinction! Mark Wahlberg takes the lead actor duties this time around as he faces certain doom in the Autobots vs. Decepticons war. But this time, the stakes seem even higher. This trailer is proof of that (one of the coolest scenes in the video above shows Optimus Prime dueling with a vicious Dinobot). Enjoy the new full trailer and come to your own conclusions on how this new Transformers war on Earth will play out.
