Firefoam
 | This article is a stub. You can help RimWorld Wiki by expanding it. Reason: New firefoam mechanics in 1.4 - also specifically how Covered in Firefoam hediff works, how its procced (just explosion or what?), how long in lasts, whether it lasts longer in foam filth etc.. |
Firefoam is a flame-retardant foam that extinguishes fire on contact and prevents fire from spreading on tiles it covers. It also gives the Covered in firefoam status to pawns standing inside, reducing Flammability to 0%. This status lasts for 15 seconds (900 ticks) after being applied, if applied again, the timer resets to 15 seconds and doesn't stack.
Firefoam is considered filth, creating a significant beauty and cleanliness penalty. Colonists will automatically clean firefoam in the home area, and it will be washed away with rain or snow.
The following release firefoam:
- Firefoam popper
- Firefoam shell
- IED firefoam trap
- Firefoam pop pack
- Foam turret
- Paramedic
- Foam spew gene ability
Firefoam is generally released in an explosion. This explosion does no damage. The explosion will put out pawns and animals that are on fire, though the foam coating the ground does not actually extinguish fires.
Analysis
Firefoam can be left in place long term as a defense against inferno cannon and other incendiary weapons. To do so the area must be roofed and be removed from the home zone to prevent pawns cleaning it.
Trivia
- To create firefoam in development mode, use the "T: Explosion" command and select extinguisher.
