The Mass Effect trilogy is a masterful science fiction adventure set in a vast universe filled with dangerous alien life forms and mysterious uncharted planets. In this dark second chapter, Saren’s evil army of Geth soldiers has just been defeated, and humans, who are still struggling to make their mark on the galactic stage, are now faced with an even greater peril…

The second chapter in the Mass Effect trilogy 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.

Once again stepping into the role of the heroic Commander Shepard, gamers will command their crew on a suicide mission in space. Players will strategically select each member of their squad, all of whom have a direct impact on the direction of the story and the squad’s chances for survival. Players will select from a motley cast of characters including the newly revealed ‘Grunt’ – a blood-hungry Krogan.

Once players have assembled their squad from amongst the galaxy’s most powerful mystics, geniuses, and convicts, they must lead them on a suicide mission to discover why humans are vanishing from the galaxy. The success of the mission hinges on the squad recruited and their loyalty to the mission. Shepard’s future depends on it.

Two years ago, Commander Shepard died and Liara T'Soni fought in a desperate struggle against the Shadow Broker to recover her former Commander. Now that Shepard is back, it's time to even the score.

Team up with Liara and confront the mysterious and sinister Shadow Broker in the latest expansion to Mass Effect 2, coming on Sept. 7, 2010 (800 Microsoft points , free on PC).
