In case you need a reminder, we at MPC are pretty big Left 4 Dead 2 fans. In fact, if you were able to make it even half-way through our review of Valve’s fine-tuned take on cooperative zombie-slaughter without giving Valve a heaping handful of your money, well, we’re pretty sure you just hate being happy. Or, perhaps you made the mistake of wasting your precious funds on pointless causes like food and your family, and simply couldn’t afford Left 4 Dead 2. In which case, everything’s fine and dandy now, because Valve’s put the game on sale at the extremely attractive price of $24.99.

The sale runs from now until Thursday, and applies not just to vanilla Left 4 Dead 2, but also to any bundles that include the game. So basically, we recommend that you pounce on this deal like a starving, family-less guy who spent his last few bucks on Left 4 Dead 2 pouncing on free samples at the grocery store. Or something.

Valve also points out that Left 4 Dead 2’s eagerly anticipated “The Passing” DLC is coming sometime this spring, and will include – among other things – multiple brand new game modes. As in, more than one. Since Valve wrote that announcement in all caps, we’re gonna assume it’s a big deal. More details soon, we hope.

Zombie hunting season is officially open, and Valve has another hit on its ESRB-compliant hands. After little more than two weeks on shelves, Left 4 Dead 2’s retail tally has slashed through the two million mark like a katana through brittle undead flesh.

“Left 4 Dead 2 is off to a great start with strong support at retail and great reviews from the press,” said Doug Lombardi, VP of marketing at Valve. “Meanwhile the title has already been played by over 1 million Xbox LIVE Gold account holders, and news regarding L4D2 DLC 1 is coming very soon.”

Valve also added that “sales to date are more than double the original title.”

As for the real zombie apocalypse, well, we're guessing that’s probably on hold. Odds are, its brain-munching participants are cemented to their screens at the moment, completely addicted to Left 4 Dead 2 just like the rest of us.

Team Fortress 2 is pretty great, but you know what would make it even better? Did you say “one or more zombies”? Yeah, us too. But instead, you’re getting a hat.

“For the first time in history, two separate Valve universes collide. That's right: it's a Left 4 Dead/Team Fortress crossover! This is not fan fiction! This is not a dream sequence! The characters from Team Fortress 2 will team-up with Bill's hat from Left 4 Dead 1!” reads a post on the TF2 Blog.

There’s a catch, though: Bill’s ridiculously regal Head Enhancement Item is only available to those who have preordered Left 4 Dead 2.
 
Honestly, though, to make such a strong fashion statement – nay, a fashion exclamation – we would’ve shelled out the full fifty smackeroos even if Left 4 Dead 2 weren’t involved at all.

Ok, not really, but you get the idea.
