Alien life rises deep from beneath the Pacific in the third trailer for Pacific Rim, which brings tons of never-before-seen footage from Guillermo del Toro's sci-fi thriller. To combat these giant Kaiju, a special type of weapon is devised: massive robots called Jaegers, which are controlled simultaneously by two pilots whose minds are locked in a neural bridge. Together, they stand as mankind's last hope against the mounting apocalypse. Watch as these monsters fight giant robots in what will prove to be one of the most epic battles of the summer movie season.
