Hellrunners

Hellrunners is a tabletop RPG about speedrunners glitching and breaking the metaphysical rules of reality the same way they break the rules of videogames. Use a death warp to get into the afterlife, use an item duplication glitch, get arbitrary prayer execution via a data overflow, find the soul of Karl Marx, perform a necromantic ritual, and use a wrong warp to get back out again!

Hellrunners is a roleplaying game for 4 to 5 players (with variant rules if you have fewer):

The Client has a mission that can't be completed through ordinary means. The Runner knows the tricks to get to hell and back. The Crowns of Hell play all the devils, angels, cops, bosses, and other bureaucrats that make everything miserable for everyone else. The Damned are everyone else, and they suffer. The Chat plays the audience watching the run on a streaming site, asking questions, making jokes, posting advice, and interacting with the runner.

Each mission plays out in one session, lasting a couple of hours. It requires zero prep from any of the players. Because each player is taking on a portion of the responsibilities that a GM would be expected to shoulder in a traditional RPG, you can put it all together on the fly. The game is designed for single-session play, but has rules for extending it to a longer arc over several sessions. All of the moves and agendas push into one another creating a fun little mechanism that drives play and produces hellish hijinx.
