THQ trades Metro 2033 codes for Facebook likes

THQ hurling cheap-to-free catalogue games like so many snowballs

THQ just can't stop giving away copies of Metro 2033. The publisher is handing out free Steam codes for the sleeper hit Oprah-style to anyone who "Likes" its THQ Demos Facebook page, not to mention including it in the cheap-as-you-are Humble THQ Bundle.

Speaking of the bundle, it's grown a few games since we initially reported on it and ends tomorrow. Now users who pledge above the average (currently $5.69) will receive Steam codes for Warhammer 40,000: Dawn of War, Titan Quest, and Red Faction: Armageddon's Path to War DLC on top of the original slate.

We'd feel pretty silly about actually paying for Metro 2033 at this point if we didn't enjoy its creepy post-apocalyptic Russian atmosphere so much, and THQ's surely banking on adding a few more fans to the series in time for sequel Metro: Last Light's release next year.
