If you picked up the latest issue of Game Informer, you will have seen these Mass Effect 3 images, albeit at a smaller size. If you haven't, well, enjoy them as nature intended, on the internet!
It's a little strange that, for a game that's all about saving humanity and Earth from an alien invasion, these screenshots are almost solely focused on killing other people.
Oh, except for the one showing Krogan Husks. That's interesting.
