The Left 4 Dead Blog has some startling statistics on how many zombies have been dispatched since the launch of Left 4 Dead 2, Valve's zombie shooter sequel. Word is:

In the first two months of Left 4 Dead 2's release, 28,981,249,043 zombies have been shot, bludgeoned, chainsawed and killed — or, for our younger readers, taken to a farm where they can frolic and shuffle around forever.

You read that correctly: 28 BILLION. To put that number in perspective:

    • The entire population of the planet has been zombified and killed 4.26 times.

    • With the average height of a zombie being 6 feet, if you stacked them end to end they would circle the globe 1,322 times.

    • If you placed 28,981,249,043 rulers end to end, they would reach 28,981,249,043 feet in the sky.

In short: That is a bucketload of dead zombies. Nice job, everyone.
