Breeders of the Nephelym is an immersive, beautifully erotic 3D adventure game centered around catching and breeding the Nephelym, an enigmatic race of monster-human hybrids.
Angry after getting scammed out of a promised solar eclipse, I channeled all the rage into development. As a result, it's time to show my latest work on the breeding system--complete with the first ever new universal sex scene, so kick mom out of your basement, 'cause it's bang'n time.

Note on Languages
This first pass is crude, most of the UI cannot be translated yet and it will be a slow undertaking to expose it all. The only language available right now is simplified Chinese as it was generously contributed by patrons.
Soon, I will open-source translations so that anyone can submit them, but keep in mind as the game progresses more dialogue will be added/changed and translations will need to be updated.
