The firefoam shell is a type of mortar shell that upon exploding, spreads firefoam in a 5-tile radius, extinguishing all fires and preventing new ones.

Crafting

Firefoam shells are made using 25 steel at a machining table and requires Firefoam to be researched. The steel cost is increased to 35 if the Classic Mortars difficulty option is enabled.

It can also be purchased from traders.

Usage

It is supposedly used for firefighting, due to the fire-extinguishing properties of the residual firefoam. It requires manual targeting to use, as colonists manning mortars don't automatically aim at fires.

However, it is somewhat cost-ineffective, as its tiny 5-tile radius isn't enough to cover large-scale fires, and it lacks the precision to be able to be dropped onto small fires accurately. Firing these shells to extinguish fires will quickly eat through your supply of steel. It cannot extinguish fires inside your colony properly as the mortar's blind spot prohibits it from hitting fires close to it.

It does allow colonists incapable of firefighting such as Pyromaniacs to help with firefighting efforts, however, which can be handy if you need more hands on deck in controlling an out-of-control wildfire.
