With "The Passing" due out soon on the PC and Xbox 360, we figured we'd whet your appetite with a rundown of the new Achievements you'll be able to earn later this week.
Let's start with the straight-forward ones we'd be crazy not to include: Surviving the campaign, playing some Scavenge, using the new weapons, playing a Midnight Riders song, and smashing up some Survivors with a Charger.
Alright. Now onto the spoilery ones. Some of these might not make sense until you play The Passing--like "Cache Grab", which involves foot lockers, a new addition to the Left 4 Dead 2 universe.
Okay. So we know one of the original Left 4 Dead Survivors is off shooting zombies in Heaven--but what are the other three up to? Covering your ass.
The "Grave Robber" achievement ties into another addition to the L4D2 universe, in the form of a new Uncommon Common: the Fallen Survivor.
And of course, we saved the best for last: the "Mutant Overlord" achievement, which you can only get by playing six Mutations.
Right about now you might be asking yourself, "What in the hell is a Mutation?" "Why do I have to play six of them?" "Are there more than six?" "Where's that smell coming from?" All good questions. Look for most of the answers in our Wednesday blog post.
