It's the mutant offspring of Condemned, Bioshock, and Oblivion set in a grungy, analog-punk world of urban decay with a unique visually based system combat/danger that directly ties in with character upgrading/customization. If any developers are interested, I'll write the whole damn thing pro-bono. If not, at least it's wasting space on the intertubes instead of my delicious brains.
What say you? Anyone else haunted by brainstorms they can never harness?
