The Fortress Awaits
A lot of light mod tweaking to remove the color grading here (brightens up the scene, as they use color grading for darkness). I changed the colors, and then added contrast back in. It's a powerful script, that.
My last screenshot of this area looked like this, and you can see it's much darker in that shot and hard to make out details.
