THQ is fast becoming one of our favorite game developers. After releasing the Humble THQ bundle a few weeks back, the company is now releasing one of their better games on the PC for free. The company is showing off the official sequel to their acclaimed post-apocalyptic title, Metro 2033, and to celebrate the developer is allowing PC gamers everywhere to download the first game, absolutely freaking free. If you didn’t jump on the Humble THQ bundle a few weeks back and did not get this game, this is a perfect time for you to do so. The game’s not your typical FPS, and while it took a beast of a machine to run when it first came out, we’re pretty sure most gaming rigs nowadays are perfectly capable of running this game now.
