Pick up a brick (right click on stone block to equip), chuck it at a rat. Like pila, an equipped brick can be thrown multiple times. I have not tested this with older versions, but it consists of 2 very simple defs and 1 patch, so it'll probably work fine (if it does, tell me so I can add those versions to the supported list.) There are three (3) lines of text in this mod, so if anyone wants a translation it would not be difficult to add.
