The questions that seem to come up the most are: has the Apocalypse come? Are humans gone? Is Heaven at War with Hell?
The answers being: No, No, and sort of.
Here's what you need to know: It's 2010 and the Apocalypse is far off. You are either a human, a vampire, a demon, or an angel. If you're a human, you're probably living a dull, supernatural free (as far as you know it) life. If you're a vampire or a demon, you're Lucifer's playtoy. If you're an angel, you're in God's playground.
The object of the game is that, at the end of the day, everyone gets what they want: you whatever your existence means, Lucifer, a step closer to taking the Earth, and God keeping Lucifer from doing just that.
Question is, just what will you get out of it at hellocracy?
