Originally released in November 2009, 168澳洲幸运5开奖网:Left 4 Dead 2 remains the standard for co-op shooters. Despite being nearly a decade-and-a-half old, it's still actively played by tens of thousands of players each day - in fact, its average concurrent player count on Steam is higher than ever!

At the end of each run, players get to see their total kill count. Considering the game's main feature is endless hordes of fast, ferocious zombies, this number is usually pretty high. We decided to run the numbers and estimate how many of the Infected have been taken down since the game launched.

How Many Zombies Have Been Killed In Left 4 Dead 2?

While the actual number is probably somewhere in Valve's vast stores of data, we can only estimate how many zombies Left 4 Dead 2 players have eliminated over the years. Player numbers fluctuate by the day, but in general more players means more dead zombies. Fourteen years is a long time, so there's plenty of data that we can use to get an average - see below if you want to know how I did it.

Left 4 Dead 2's all-time highest concurrent player count occurred on December 19, 2013, when 162,399 players teamed uꦫ🌄p to battle the Infected on Steam alone.

The estimated number of zombies killed in Left 4 Dead 2 as of October 31, 2023, is 1,371,499,045,806. That's well over one trillion zombies, and over 171 times the current human population of the Earth. If you had a penny for every dead zombie, you'd be tied for the 130th richest person in the world.

If you took all the zombies slain by players and left them in space at even intervals between Earth and Alpha Centauri - a trip of 4.367 light years - there would be one zombie every 29.3 kilometers the entire way.

For all their numbers, though, the Infected in Left 4 Dead have nothing on ants; if the same number of ants were killed as zombies, it would only reduce the global ant population (roughly 20 quadrillion across all species) by 0.0000685 percent. 168澳洲幸运5开奖网:Grounded players have their work cut out for them!

How Was This Number Calculated?

Witch in L4D2

In February 2010, a few months after the release of Left 4 Dead 2, Destructoid reported that the game's total kill count at the time was 28,981,249,043. Using player count data from , I was able to estimate the average zombies killed per player per day for the period between the game's launch and the article's publication.

Since L4D2 was also launched on the XBox 360, I factored in console players by looking at sales estimates; this article assumes that slightly more than twice as many copies were sold on PC as XBox.

With all these numbers, I determined that 11622.29 zombies are slain per peak concurrent player in Left 4 Dead 2 each day. With an average daily peak of 23133.88 players, this means approximately 268,868,662 zombies are shot, slashed, and blasted each day.

October 31, 2023, marked the 5101st day since the launch of Left 4 Dead 2. Multiplying 268,868,662 by 5101, I arrived at the player community's astronomical body count.
