Out of all the games we managed to squeeze into our heads during E3's three days, BioWare's Mass Effect by far and away left us the most impressed, and our pants most soiled.

Now, two months after we were wowed in Los Angeles, you can also lay your eyes on the jaw-dropping Xbox 360 demonstration shown at E3. The E3 footage shows off Mass Effect's impressive facial animation and lighting systems, as well as some thrilling sci-fi exploration and combat gameplay we can't wait to get our hands on.

Mass Effect explodes onto Xbox 360 early next year. Enjoy the footage.
