Biblical apocalypse? A while ago I found a site with an then-not-finished video series depicting the events writ in the book of Revelations. I can't find it again, and all I remember from finding it the first time is that its animation style was reminiscent of Pokemon, and that I didn't realize it was about the End Times until I started watching it, so I don't think it had "Revelations" or anything similar in its title. It was also quite gruesome.
