Here's a few Metro 2033 screenshots that apparently exhibit Direct X 11 features, so they will be PC shots obviously. Both 4A-Games and NVidia seem to be trumpeting the 'most advanced' DirectX 11 effects yet, but that seems odd to em as NVidia still don't have any DirectX 11 Hardware.

"Our engineers have been working closely with 4A Games to ensure that Metro 2033 takes full advantage of some of the spectacular effects made possible with the next generation of DX11 hardware," said Tony Tamasi, Senior Vice President of Content and Technology at NVIDIA. "The 4A Engine is one of the most advanced game engines we’ve ever worked with, and with DX11 enabled, Metro 2033 is undoubtedly one of the best looking PC games of 2010. Combine this with NVIDIA 3D Vision and PhysX and you will experience mind-blowing visuals."

There's also a trailer embedded below which I hadn't seen before, 4A-Games post-apocalyptic shooter is coming to PC and Xbox 360 on March 19th.
