Sorry - sort of but not entirely related: Swift, do you know ruffly when Infernal Realm might hit the Offical KF2 Roster? Or are you just as in the dark as most the community?

Avoiding any prior listed favorites-

Movies/TV:
-Jacob's Ladder
-Dark City
-the Shining (as a film; Steven King as an author is not my favorite)
-Master's of Horror Series; particular the unaired 'Imprint'- very disturbing
-Rob Zombie films\remakes

Literature (often film adaptaions exist but vary in delivery):
-Weathering Heights- Emily Bronte
-the Witch House, the Mountains of Madness, the Lurker at the Threshold, Pickman's Model- H.P. Lovecraft stories
-The Road - Cormac McCarthy
-Saga - comic book series

Video games of worthy mention:
-the Evil Within
-Bioshock
-Twisted Metal Black
-Dead Space

Although I second Refurbished variants of your KF1 maps, I'd also like to see a Rapture Ballroom (ie: Bioshock Infinite's Burial at Sea DLC) styled level. I was going to attempt it myself but I think my talents need some smaller projects to practice on first.
