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.

In Overlord, players will take Commander Shepard and his crew to investigate a Cerberus research base that has mysteriously gone silent. They arrive to find that Geth troopers have overrun the base. The sole survivor paints a dire picture: an experiment to fuse a human volunteer with a virtual intelligence has created a dangerous hybrid VI Overlord. The rampaging VI Overlord has already attacked three other Cerberus bases, taking control of any technology it finds—and unleashing hostile Geth across the planet in the process. Unless Shepard can infiltrate the VI’s fortress and shut it down, this homicidal intelligence will beam itself off the planet and wreak havoc on other systems throughout the galaxy.
