Well here's something you don't see every day: Turtle Rock has released a brand new campaign for the original Left 4 Dead that never made it into the final product. Apparently it isn't perfect, but it's playable from start to finish.
The folks over at PC Gamer came across a recent update on the Turtle Rock blog. That's the team responsible for the original Left 4 Dead and, more recently, the similarly-themed cooperative shooter, Evolve. Since we've got no word on whether or not a Left 4 Dead 3 will ever come our way, for the time being this is your best and only chance to experience something new from the series.
The campaign is called "Dam it" and, according to the announcement, it strays from the game's usual motto of "everybody stick together." You'll actually stand a better chance at completing this mission if players separate from time to time, so good luck with that!
If you own the original Left 4 Dead, then all you have to do to grab this free campaign addition is get to downloading. There's a special page set up at the third-party site, Auger Resources, where you're given two ways to add "Dam it" to your game. You can either plug it into your game with the automatic install option or you can go manual, which will require you to unzip the .vpk file and copy it into your Left 4 Dead folder called "addons." Again, this is a third-party site, so we encourage caution.
Once you get the campaign add-on loaded into Left 4 Dead, you can start playing right away. Again, it's stressed that this is an incomplete bit of code, so don't be too upset if there are some weird quirks here and there. The pack also comes with a couple of survival maps that never shipped for the game, so be sure to check those out, too.
As for where "Dam it" fits in the story, the update states that it bridges "Dead Air" and "Blood Harvest." So if you felt like there needed to be some connective tissues between those two missions, now you know why.
If you head on over to that download page, you'll also see a nice little map of the areas, complete with some information about what your objectives will be. It actually looks like a pretty big map with a lot of interesting stuff going on, so we think it's rad that Left 4 Dead fans will finally be able to experience it.
In case you're wondering about known issues with the mission, here's a rundown of what you can expect to not work as intended.
-Fire, smoke and explosions don't trigger panic events in the hangars.
-Zombies do not crawl all the time in the orchard.
-Farm house mob does not spawn in the far side of the woods.
-Covered bridge does not collapse with explosions.
-Burned forest area is missing wandering fires.
