Adds three single shot launchers in the vanilla style for increased variety.
Furnace launcher: Flash heats an area and deals very high flame damage in a medium area.
Igni launcher: Incendiary warhead that deals low flame damage and starts fires in a large area.
Pin launcher: Deals high sharp damage in a small area. Very effective against structures.
Costs are proportional to effectiveness. Rockets can still miss spectacularly (vanilla mechanic), especially the Pin with the much smaller effective area.
