BioWare today officially announced Mass Effect 2, the sequel to the acclaimed sci-fi RPG Mass Effect.

"We're going to surpass the extraordinary gaming experience we brought our fans in Mass Effect by delivering intensified combat and expanded weapon options as well as increased depth of planet exploration, all while delivering a powerful, emotionally engaging story," said Dr. Ray Muzyka, General Manager and CEO, BioWare and General Manager and Vice President, EA. "Mass Effect 2 is shaping up to be an unforgettable RPG-shooter experience, taking players on a non-stop roller-coaster ride filled with stunning plot twists and no-holds-barred action."

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.

It's also been confirmed that the game is coming to Xbox 360 and PC in early 2010. The press release makes no mention of the PlayStation 3.
