Those that are 100% super amazing excited (it's a technical phrase, trust us) for The Passing will be glad to know that it has finally dropped on PC! Unlike the Xbox 360 version, the PC version is available for a whopping $0.00. The Passing includes a new game mode that randomizes game types each week, new weapons, a new campaign, new achievements and more. It's a whopping gig in size, so we suggest you start downloading right away! Oh and there's even a (sort of) cameo message from a character in a different zombie game.

To commemorate the release of The Passing, Valve has marked Left 4 Dead 2 down from the normal $30 price tag. Those wanting to get into some zombie killing mayhem can do so for a mere $20 this weekend. Considering that the original price point on release was $50, we can say that this is a stellar deal for those that have not picked up Left 4 Dead 2 yet. You can also play with the developers by adding certain tags revealed on the Left 4 Dead blog. Happy zombie hunting!
