While drowning in an ocean of famished zombies attempting to grind your brains to make their bread, paying attention to the blips and bloops of tiny achievement indications is a tad difficult. Fortunately, according to Valve's newly released list of Left 4 Dead achievement statistics, you're not missing much.

Oh sure, Valve has loaded its game with wacky (and easily pun-able) methods of undead dead-making, but at this early stage of the game, only a small percentage of players have truly lived during their short spurts of undeath.

Especially noticeable, not a single player has managed to slay their way to the "Zombie Genocidest" achievement, which forces players to sacrifice 53,595 hapless zombies in order to appease its dark whims.

On the opposite end of the spectrum, 73.9% of players have laid claim to the "Drag and Drop" achievement -- wherein, you're simply required to chop through a Smoker's tongue before one of your buddies takes any damage.

So, which L4D achievements adorn your trophy case? Is your zombpocalypse training nearly complete, or are you only beginning to learn your ABZ's?
