Man, you guys freaking hate zombies. In the first two months since Left 4 Dead 2 launched, players of Valve’s undead-filled first-person shooter have shotgun blasted, cricket batted and frying panned a grand total of 28,981,249,043 zombies.

Yes, it may seem like an ultimately pointless stat to you, but it gives me an excuse to show off screens from “The Passing,” a brand new Left 4 Dead 2 campaign coming in March. No price revealed for this downloadable campaign yet, but we do know that it will involve the L4D2 cast (played by you) meeting up with the survivors (as non-playable characters) from the first game. Bill shall return!

There’s also a new uncommon common infected, the Fallen Survivor, who will occasionally shed a useful item, like a badly needed health kit, for example. Oh, and the first Left 4 Dead game will get an add-on about a month later.

All clear? Good. Now have some “The Passing” screens:
