In Heaven or Hell you fight for Souls and you fight in the name of your Lord of Heaven or Hell! The harder your fight is to win a Soul the greater benevolence your Lord bestows upon you. However, a soul saved can be tempted, and a tempted soul can be saved. Use the Powers and the world to your advantage and crush your opponent.
The game is in early development. Inspiration is among others from Dominion. However, I've read about the games Hero Realms and Cthulhu Realms and there are similarities. I've yet to try them, though.
The game is being tested.
