Published by Microsoft Game Studios, "Mass Effect" will be exclusively for the Xbox 360 video game system.

As the first human Specter – sworn defenders of galactic peace – your mission is to halt the advancing armies of a legendary agent gone rogue. But as you lead your elite team across hostile alien worlds, you will discover the true threat is far greater than anyone imagined.

Mass Effect 2:

Two years after Commander Shepard repelled invading Reapers bent on the destruction of organic life, a mysterious new enemy has emerged. On the fringes of known space, something is silently abducting entire human colonies. Now Shepard must work with Cerberus, a ruthless organization devoted to human survival at any cost, to stop the most terrifying threat mankind has ever faced.

To even attempt this perilous mission, Shepard must assemble the galaxy’s most elite team and command the most powerful ship ever built. Even then, they say it would be suicide. Commander Shepard intends to prove them wrong.

Earth Has been taken, the galaxy is on the verge of total annihilation, and you are the only one who can stop them. The price of failure is extinction.You are Commander Shephard, a character that you can forge in your own image.

You determine how events will play out, which planets to explore, and whom to form alliances with as you rally a force to eliminate the Reaper threat once and for all. How you wage this war is completely up to you: go into combat with guns blazing or use cover to plan a more tactical assault. Utilise your squad to full effect or take a lone wolf approach.
