Those screenshots look really dire; certainly much worse than RAGE. And they seem to bare absolutely no relation to the Doom universe. Wrecked cars? Cranes? Large outdoor areas? It doesn't look like it's set on Mars, that's for sure.
I don't think they're genuine, as they look really, really bad... it looks more like a mod for Doom 3. For starters, why would any major gaming company release images as such a low resolution and without more hype behind the reveal?
