Want a download code to get Metro 2033 for free on PC? All you need is a Facebook account and one little "like" on the official Metro (THQ) page.

THQ is running a promotion for the upcoming game, Metro: Last Light, in which they'll gift you with a downloadable copy of the original 2010 release, Metro 2033, in exchange for a "like" on the game's official Facebook page. Doesn't sound like such a bad deal, right?

The Metro games feature a mix of first-person shooter gameplay with survival horror elements, mainly set in the metro system of a post-apocalyptic Moscow. In Metro 2033, players have to survive against mutants and other humans in a dark, foreboding environment. There is limited ammo, the need to change filters in one's gas mask every so often, and a lack of a visible health bar, so players' resourcefulness are definitely put to the test in this game.

Metro: Last Light, the sequel to 2033, will be out in March 2013 and will feature similar gameplay, but with more locations and improved mechanics. It will also have voice-acting by actors such as Lance Henriksen, Nolan North, Khary Payton, and funnyman Patton Oswalt. For more of a look at Last Light, an article on Kotaku offers impressions based on a preview event. Check out the videos for both games below to get a sense of the gameplay.
