Some more thoughts I had last night:
use range damage notes
4 8" 3D6 uses whatever spread pattern and fire rules the player has.
If the Manly Man carrying this weapon rolls a 2 or lower for Skill, he succumbs to temptation and drinks the beer. Until you find some new beer to power it, the flamethrower is useless.
CHUG! CHUG! CHUG!
Once per game, the Manly Men may drink all their beer at once, gaining a second action and +1 to all damage rolls. However, they get -1 to skill and damage for all parries and counterattacks, and at the end of each turn they stumble 1D6 inches in a random direction (or, for extra fun, a direction chosen by their opponent). The effect lasts for 1D6 turns, and then all of the Manly Men take 1D6+1 hangover damage. Meant to be the Manly Men equivalent of the Britannian "for queen and country" ability.
Just one random act of violence can brighten your day. Especially if it involves explosives.
