BioWare showed off a new Mass Effect 3 trailer this past Saturday at the VGAs. It features an awesome battle of a Reaper going against a Thresher Maw.

Shepard is on footing leading an attack against the Reaper, several attack ships are flying in taking on the Reaper – a sentient robot hellbent on destroying everything in the galaxy but during the attack a Thersher Maw, a giant worm that tunnels through the ground, attacks the Reaper.

It looks like Mass Effect 3 will be full of intense moments as this conclusion this May March 6th, 2012 for PC, PS3 and Xbox 360.
