The Achievement list for Valve's zombie-braining sequel Left 4 Dead 2 has been revealed, bringing with it verification of the yet-to-be-official campaigns, Hard Rain and Dead Center. The Achievements also make mention of brand new items, which I will now spoil for you all (so stop reading if you're one of those "SPOILARZ" bitches).

First of all, there seems to be some sort of new weapon called the Boomer Bile Bomb. While no details are given, one would assume it works very similar to the Antlion pods in Half-Life 2, with Survivors throwing them to lure away the infected. A defibrillator is also mentioned -- a new way to bring back lost allies?

If you don't like surprises, you can hit the jump for the full Achievement list.
