This is primo territory for Gun. A new edgy horror story is right up their alley. Plus visual bugs and glitches would be next to nonexistent so they could really focus on the gameplay. I personally would add a peek function that could be used for a few seconds every few minutes to give a nice glimpse of the ultra HD environment but make it very risky because it could lead to your death. There is so much potential here for them. It would need too notch audio though. I want to hear footsteps, moving water, rustling leaves, creepy monsters, and general creepy noises.
