Just a quick update in case you haven’t spotted it yet in your Internet travels: day 3 of Steam’s mega-sale of everything THQ slashes the price of Metro 2033, the creepy first-person shooter where bullets act as currency and everyone owns a gas mask. If using bullets to buy groceries appeals to you, check it out. Sadly, we’re stuck living in a world where bullets do not equal cash and a zombie apocalypse has not yet thrust us into a real-life Left 4 Dead situation, so you’ll have to fork over $13.60 worth of our regular, boring, pre-apocalyptic money to get your digital-downloading paws on Metro 2033. Here, have a link to the Steam store. Enjoy!
