A trailer promoting this January 18's release of Mass Effect 2 on the PlayStation 3. In this dark second chapter of BioWare's sci-fi trilogy, Saren's evil army of Geth soldiers has just been defeated, and humans, still struggling to make their mark on the galactic stage, are now faced with an even greater peril... The game takes you to the darkest reaches of space, where you must uncover the mystery behind the disappearance of humans across many worlds. Prepare yourself for a suicide mission to save mankind. Travel the galaxy to assemble a team of soldiers and combat specialists, and launch an all-out assault on the heart of enemy territory. Success - or failure - depends heavily on the crew you assemble and their loyalty to you and the mission.
