Jack Wall, the composer who scored the first Mass Effect, will return to do the second act as well. The game will feature nearly three hours of orchestral arrangements.

In addition to the ME series Mr. Wall has also worked on:

• Neopets: The Darkest Faerie (2005)  (cinematic scoring)
• Jade Empire (2005) 
• Myst IV: Revelation (2004
• Splinter Cell: Pandora Tomorrow (2004)
• Wrath Unleashed (2004) 
• Unreal II: The Awakening (2003) 
• Myst III: Exile (2001) 
• Evil Dead: Hail to the King (2000)

“Working on the Mass Effect franchise has challenged me to create music beyond what I’ve written before,” said composer Jack Wall.”With Mass Effect 2, the story is even more engrossing and affecting, so it was important for me, along with my team of composers Sam Hulick, David Kates, Jimmy Hinson, and music implementation by Brian DiDomenico, to develop a score that complemented the scope and intensity of the gameplay while captivating the players and drawing them deeper into the story.”

The Mass Effect 2 soundtrack will be available for purchase from digital retailers on January 19, 2010.

Mass Effect 2 is scheduled for release on the Xbox 360 and PC on January 26, 2010 in North America and January 29, 2010 in Europe and has been rated ‘M’ for Mature by the ESRB and ;18+’ by PEGI (so parents be aware).
