The Left 4 Dead series has some great expansions, but one that never saw the light of day would have trumped them all, especially for fans of the awesomely satirical horror film Cabin in the Woods.

Director Drew Goddard revealed in a reddit ask-me-anything session today that he had been working on getting a Cabin in the Woods expansion in Left 4 Dead 2. Warning: Cabin in the Woods spoilers lie ahead.

"We actually were going to do a downloadable L4D2 expansion pack, where you'd fight in the Cabin world, but then MGM went bankrupt so the delay squashed it," Goddard wrote. "But the people at Valve were still cool enough to let us use some of their monsters to fill the cubes in the background (I had a lot of cubes to fill)."

Yes, apparently you can glimpse some Left 4 Dead infected when our heroes are headed down the elevator shaft into the facility. And just to make us want it even more, Goddard added some details:

"By the way – the game was gonna be amazing. You were gonna be able to play in both the upstairs Cabin in the Woods world and the downstairs 'facility' world with all the monsters. Believe me, I HATE all video games based on movies, they always suck, but porting Cabin into Left For Dead felt like the right fit. It pains me that it didn't happen."

Oh, it pains us too. By the way, we've also just learned that Steam Workshop will be added to Left 4 Dead 2 in October. Any ambitious modders out there?
