Industrial foam cannon

So I picked my favorite profession Radio tower technician and noticed a new item the foam gun so I tested it and it created a trap called “foamcrete” I tested it by spawning a zombie and herding it into the foamcrete and it slowed it a lot! Like more than windows! I think this could be useful for creating Zed killing stations and clearing cities. One problem, I cannot figure out how to get more ammo. Does anyone know?

Looks like a newer aftershock item, the item browser doesn’t know of crafts or drops for the pressurized tanks. Might be lootable somewhere.

Just checked and it is aftershock. Still cool even if it isn’t in the base game I guess I will just roleplay as a TranStar survivor in aftershock.

As far as i know, you can find book with 2 recipes in it, one of which is foam gun ammo. Another thing is, if you stack 3 shots on the same place, it will create foamcrete wall, 2 shots is better slow than one shot too.
