Left 4 Dead 2 Achievements Reveal Final Two Campaigns

The list of Xbox 360 Achievements for Left 4 Dead 2 appear to have just "confirmed" the game's two, still-to-be-officially-announced by Valve final campaigns and revealed new items, new infected and some pretty ridiculous in-game tasks! The 50 new Achievements don't really venture into spoiler territory—there are no plot points revealed below. The list of Achievements looks to verify the leaked campaign posters (view below, after achievement list) for "Dead Center" and "Hard Rain," possibly ordering them in sequence as the first and second-to-last campaigns in Left 4 Dead 2.

Also apparently confirmed is the Boomer Bile Bomb, a grenade weapon that looks to be gathered from slain infected CEDA agents. Our best guess is that the Bile Bomb works in the Survivors' favor, sending a horde of zombies after the target in a fashion similar to the Antlion pheromone weapon seen in Half-Life 2. The Achievements even make mention of a defibrillator twice, which looks to revive dead Survivors once they are killed in battle. Check out it all below and stay tuned for more info on Left 4 Dead 2 as it nears it's November release date, right here at PlanetXbox360.com.
