Topic: Left 4 Dead 2 Review
I doubt many people, outside of those who actually work at Valve, had any idea that Left 4 Dead, the zombie-slaying gore-fest built off the same engine as Half-Life 2, would be as big of a hit as it was. After its release almost exactly a year ago (wow, really?), Left 4 Dead parlayed its warm critical reception into a bona fide commercial bonanza, selling around three million units across a few different platforms.
