Welcome to the Fluxfall Jam!

Fluxfall Horizon is a fast and light RPG that thrusts “lancers” from the future into countless parallel worlds. The core rules are based on the Apocalypse Engine and geared towards one-shot or short-campaign play. 

Since the game only has five core stats, 11 “Moves” and 10 playable Types, it is ripe for easy play, tweaking and hacking. This jam is aimed at handing the game over to you to see where you can take it!

Here are some areas where you can get started:

  • Types and Factions: The 10 playsheets cover the 10 “Types” that a player can choose from, and they span five different Factions. There are plenty of new possibilities for Types and Factions within the setting.
  • Moves: The core rules for Fluxfall keep it tight with just 8 “diagetic” moves and 3 metagame moves. But the sky is the limit on changing the feel of gameplay with new or modified moves.
  • Quantum Powers: Lancers can unlock 18 powers as they become more and more disentangled from the Continuum. These are meant to give players a sense of power and the ability to synthesize crazy situations as their character spirals towards sci-fi oblivion. But there are so many more powers you could probably come up with.
  • Home Earth: The game’s artwork and base setting starts lancers off in the 24th century (AD 2390) and lancing to Earths in that time period. Of course, once they lance, the Earth can resemble any period in history. But the home Earth is still important since it frames the lancers’ point of reference for everything they see and interact with. They’re used to living in a utopian future. But what if their home Earth were another time?
  • Scenarios: The core game comes with a few scenarios that follow a general template containing tables and NPCs for GMs to use to generate their own specific details. There is no limit to the number of situation sandboxes you could generate.
  • Alternate Earths: Similar to scenarios, alternate Earths in the core game present a more generalized sandbox of rollable tables that detail a world dominated by a single theme or culture. Come up with one based on your favorite culture, or even some media that you are intimately familiar with!
