I'm sure BioWare will ask him to pull these down very soon, but thanks to a blog entry by artist Robert Simons, we now have our very first glimpse of Mass Effect 3. These six pieces of concept art depict Normandy 3's engine room, deck, and commander office, as well as a mining planet and some nasty-looking alien creature.
Updated: While they certainly look official, it looks like these images are fakes. Sorry for the confusion!
