Finally, after so many live action trailers, THQ has finally cut a gameplay trailer for Metro: Last Light. This two minute video shows off 4A Games' impressive engine, and how it renders the horrifying beasts that will kill you in the upcoming FPS.
If you pay attention to the end of the video, you'll see that THQ is offering the original Metro 2033 for free. You can pick up a free PC copy of the game by visiting the game's Facebook page. It's even cheaper than supporting the THQ Humble Bundle.
