Angelus 2: Holy Night

Angelus 2: Holy Night is the cancelled sequel to Enix’s Angelus: Akuma no Fukuin, once in development by Asmik Ace Entertainment with such names as Yuzo Koshiro and Hiroyuki Kitazume working on the project, planned to be released for PC Engine and PC-98. Angelus 2 would have continued the story, left unfinished with a huge cliff-hanger.

Somehow a CD-R containing data from this unreleased sequel was found by collectors, who later uploaded the content online. It seems the main plot was complete and you can listen to audio files (in Japanese) to understand what would have happened in the final game.
