Valve have published achievement statistics for their popular zombie shooter, Left 4 Dead.

The list shows the percentage of players that have accomplished each of the achievements, and range from Brain Salad - Make 100 headshot kills to Burn The Witch - Light a Witch with a Molotov.

The race is on to become the first to achieve Zombie Genocidest, which involves killing 53,595 of the infected.

The only other achievement that nobody has mastered is Lamb 2 Slaughter - incapacitating a survivor who has entered and left a safe room.
