The firefoam popper is a one-time use device that will extinguish all flames in its radius when it pops.


A firefoam popper is triggered in one of two ways:

  • It is triggered automatically when it catches fire.
  • It can be triggered manually by a colonist directed to it via the mouse right-click.

Once activated, it will spark for about two seconds before it bursts into a spray of foam extinguishing all flames in a 10-tile radius. It is capable of extinguishing walls on fire, though the walls will block the foam, preventing the popper from extinguishing things behind the wall. Pawns on fire will also be extinguished.

The explosion does not damage structures or colonists, but fully depletes all personal shields within range except those right next to it.


The residual firefoam prevents fire. This provides very effective protection against inferno cannons and any other type of incendiary weapon. To intentionally leave firefoam in place, remove the home area to prevent colonists from cleaning it up. The area would also need to be roofed because rain and snow quickly wash away firefoam, in about two game hours.

Although firefoam fireproofs an area, it makes for an ugly environment. Firefoam indoors has beauty of -25; outdoors it has beauty of -7.

Pawns passing through firefoam move about 25% slower.


The Firefoam Popper is best used when put in warehouses, as it will prevent your valuable items catching fire and burning.

As it can extinguish walls, it can be a stopgap solution to prevent wood walls from catching fire, before you replace them with less flammable walls, preferably made out of completely non-flammable stone.

Another strategic way of using firefoam poppers is to keep a large number of uninstalled firefoam poppers at hand. When needed, simply install one popper near a fire. This can help extinguish large areas of fire efficiently, and also slows fire spread, though it is rather costly.

As firefoam poppers deplete shields, it can be used as a countermeasure against shielded enemies. The popper can be triggered, instantly destroying the shields of enemies and leaving them vulnerable, while sparing the shields of allies standing right next to it.
