Infaernum is a rules-lite RPG focused on apocalyptic themes. Everything starts with a major event: a prophecy that triggers the end of times. Over seven days (in the narrative), players must face all challenges and reach the promised land before the end of all things, facing the four horsemen and other tropes of the Book of Revelation. Or not. In this highly original game, you define your own vision of the Apocalypse. It can work with any campaign or setting for any system besides the standalone premise presented by the game. That means you can simply use Infaernum on top of your current RPG campaign, whatever system that might be, to explore an end-of-world scenario. It's essentially your doomsday device and toolbox. The core also includes a vast collection of optional rules, supplements, and settings that make Infaernum the ultimate doomsday device. You pick and choose what you want to use according to how you want to play at any given moment.
