Heat 
The world is full of prying eyes, surveillance equipment, and informants. Anything you do might be witnessed, and there’s always evidence left behind. To reflect this, your crew acquires heat as they conduct missions. After a mission or conflict with an opponent, your crew takes heat according to the nature of the operation:
- 0 heat: Smooth & quiet; low exposure.
- 2 heat: Contained; standard exposure.
- 4 heat: Loud & chaotic; high exposure.
- 6 heat: Wild; devastating exposure.
Add +1 heat for a high-profile or well-connected target. Add +2 heat if killing was involved (whether the crew did the killing or not—bodies draw attention).
The director marks heat levels on the heat tracker on their sheet.
When your heat level reaches 9, you gain a threat level and clear your heat (any excess heat “rolls over,” so if your heat was 7 and you took 4 heat, you’d reset with 2 heat marked).
As your threat level rises, the conspiracy begins to see you as a danger and take specific steps to counter or eliminate you. If your threat level ever reachs 5, the conspiracy moves to destroy the crew with overwhelming force.
Also, your threat level contributes to the severity of the entanglements that your crew faces after a mission.
Designer note
Threat level 5 is really "the game is over, and you lost by calling too much attention to your crew." If it makes narrative sense, you can trigger a climatic showdown with the most dangerous elements of the conspiracy. You could also let surviving agents escape and start up a new crew with no upgrades (not even the usual starting ones). Hopefully they've learned their lesson, because this new crew will have to work very quietly while they build their crew back up.
