Valve has published public Achievement statistics for its latest zombie shooter, Left 4 Dead, on the Steam website.
The statistics show the percentage of total players (of the PC version only, we assume, since the data is collected through steam) to unlock each Achievement in the game.
The most common Achievement is "Drag and Drop - Rescue a Survivor from a Smoker's tongue before he takes damage."
No players at all have managed "Zombie Genocidest" yet - you need to kill 53,595 Infected for that, so we suspect it's only a matter of time.
Perhaps the most surprising stats are those for completion. Only 0.2 per cent of players have managed to survive all campaigns on expert, and the individual campaigns have only been survived by between 19.5 and 29.7 per cent of players.
Shape up, people. They're only zombies.
Left 4 Dead is out now for PC and Xbox 360 and we really liked it.
