Here's the second teaser.
BEFORE
(A security camera shows a traffic circle in the middle of a bridge; that leads towards the Big Ben. The streets were covered in traffic. Horns are honked simultaneously as passengers try to get through. A plane is seen flying through the air.)
--
AFTER
(The camera is now laying on the ground, sideways; still in good shape, but covered in dust. The streets were deserted. There are a few cars still on the bridge; burned or still on fire. The sky was covered in clouds. Then, suddenly, the SSV-2 Normandy is seen flying across the cloudy sky. The ship then fires its Thanix Cannon at a location near the damaged Big Ben; creating a small explosion.)
