I have released 2 weeks ago a new Kontakt library - Alternate. It's a library that has very dark, dystopian, percussive and experimental sounds and it comes with a version for the full version of Kontakt 7 and Kontakt 8. Both versions contain 622 presets spread over 6 types of instruments.
The library is also part of the new Into the Dark bundle for those seeking less happy sounds
