A friend of mine from 2K Marin has been working on his first indie offering for the past few months, and it looks like he's finally announcing/greenlighting/etc. 
  
The game's called Eldritch, and it's a first person roguelike with a Cthulhu mythos vibe, plus stealth and cool mobility (mantling, power slide). Basically Call of Cthulhu: Dark Corners of the Earth meets Spelunky.

Seems like a good fit for the Idle Thumbs emergent narrative crowd.
