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.

The Kasumi – Stolen Memory PDLC pack will introduce Kasumi Goto, the galaxy’s most enigmatic and cunning master thief. In addition to being able to recruit Kasumi in all new missions, players will be able to utilize her special skills as a member of Commander Shepard’s squad throughout the entire game. The Kasumi – Stolen Memory PDLC pack will be available on April 6, 2010 for the Xbox 360 at a cost of 560 Microsoft points, and on PC for 560 BioWare points or $7.

“Mass Effect 2 is BioWare’s highest Metacritic game to date, and we are excited to be able to expand that experience by introducing another engaging new character in Kasumi,” said Aaryn Flynn, Studio General Manager for BioWare in Edmonton. “Kasumi – Stolen Memory is a testament to our promise to continue to provide fans with new, compelling, high quality post-launch content.”

Cerberus has procured the service of Kasumi Goto, the galaxy’s most enigmatic master thief. In return for her help, Kasumi has asked for Commander Shepard’s help on a dangerous heist to infiltrate the vault of a deadly master criminal named Donovan Hock. Players must gain Kasumi’s loyalty on the planet Bekenstein, where Hock is throwing a party for some of the galaxy’s richest and most deranged criminal minds. The mission: recover data of great importance to Kasumi, and to the galaxy at large. In addition to this new mission, players will also receive a new research upgrade, one new weapon, and a new achievement in this PDLC pack.

Prior to the launch of Kasumi in April, also being released on March 23 through the Cerberus Network is the Firewalker DLC pack, which includes five heart-pounding missions taking place on five uncharted worlds. Players will be able to explore planets and engage in combat in the new Hammerhead hover-tank.
