Can you make a flamer twin linked? How would Twin linked work with the Flame quality?

With a twin-linked flamer I would simply use a 60 (or maybe 45) degree arc for the flame cone instead of the usual 30 degrees and make it hard (-20) to escape the flames.

I would say 45 degree plus it would be a volatile weapon use. The its got hot rules for the plasma weapons sounds like a logical choice here to indicate the dangers of using such a weapon.

I would leave the fire arc as is but force two agility tests to avoid the attack and add overheat to the weapon.

Since normal twin-linked weapons add +20% to hit, simply flip the numbers...

-20% to the Agility test to not get hit, stacking with Cleanse and Purify talent if the crew has it.

Probably add about 2 to the damage, double the fuel consumption and reload times.

Alternately: Failure of the Agility test by 2 or more DOF = hit TWICE!
