Heist generator: prepping scores that don't fall apart on the first failed roll

[eserlan]

Heists are notoriously tricky to prep for a tabletop session. If you map out every hallway and guard, it turns into a brittle script that falls apart on the first bad roll. If you keep it too loose, you end up improvising the entire security grid and panic-closing doors mid-scene.

Following our guide on how to run a heist in a tabletop RPG, I built a dedicated Heist Generator to prep playable situations rather than rigid plans.

Instead of scripting how the players are supposed to break in, each generated job sets up interacting obstacles:

• GM Quick Reference: Seven one-line bullets covering the objective, primary obstacle, hidden factor, point of no return, in-scene pressure, complication, and escape problem so you can run the whole score at a glance.
• Concentric Security Rings: Layered obstacles from the perimeter inward, each with visible tells, distinct access methods, and active patrols.
• Point of No Return: Taking the prize immediately escalates the alert and closes off an entry route, forcing the escape to operate under completely different rules.
• Interactive Alarm Ladder: Four progressive alert stages with fiction-first complications instead of an instant party wipe.
• Flashback Opportunities: A menu of retroactive preparations players can cash in during the run to handle surprises.

It works across different genres (fantasy, cyberpunk, cosmic horror, sci-fi) and is also available directly inside campaign vaults to tie into your existing factions, locations, and NPCs.

When you run heists at your table, do you prefer giving players a full floor plan upfront, or letting them discover security details through flashbacks during the run?
