Okay, we won't deny it -- the first TV spot for Left 4 Dead 2 is pretty cool. After all, it's got the four survivor characters in a baseball stadium filled with the infected undead, one of which gets knocked into the bleachers (or at least a few feet through the air) by a baseball bat. But as much as it's an advertisement for the game, it's also one for GameStop, driving home the fact that the American baseball bat is available only through pre-order at the retailer. Good for them!It's a bit of a downer, though, for those who've reserved the game elsewhere. Or what about the people who just walk into a store on release day to snap up a copy? We've got it! The next ad should feature the survivors being ripped apart by zombies, with the tagline "Pre-order or Die!" We mean, a company's eventually going to go there someday, right?
