Of course, it's what you don't see in these shots that you really need to worry about. For example, the mutants that lurk in the tunnels just beyond the limits of your underground city. Or the "terrible impending threat" that requires you travel to "the heart of the Metro system" in a "desperate mission" to "warn the remnants of mankind."

Recently picked up by publisher THQ, Metro 2033 hits PC and Xbox 360 in early 2010.
