Worried about whether or not Mass Effect 2 will be up to par with the original? Watch this.

Ogle the giant galaxy map, and, better yet, the distinctive looking planets and new navigation system. Marvel at the interrupt system, which finally lets Shepard be an asshole in real time. And let this tidbit give you chills:

Permanently? We love you, BioWare.
