I've arranged a complete playlist of Viz's 1997 release of Night Warriors: Darkstalker's Revenge OVA series. Each episode is broken off into 4-5 parts. The OVA consist of the original 4 Episodes that were released on VHS. The audio is Japanese, with English subtitles.
Night Warriors: Darkstalker's Revenge Playlist
I've just finished watching all the episodes myself, I really enjoyed how they managed to add each fighter (even if it was breif) in. Also, want to give credit to YouTube User FunYum2032 for uploading these videos.
Enjoy.
