I am starting over.........again and I want to make a heavy weapons/demolitions/melee guy. I looked on the wiki for the weapons but I still have some unanswered questions.

1) Does the plasmathrower get treated like a regualar flamethrower with the heavy weapons perk bonus?

2) Does the missile launcher get both the heavy weapons and the explosive perk bonuses or just the heavy weapons?

3) Same question concerning the Fatman.

Thanks in advance for any advice form people who have tried these builds.

Being a thrower does no change what perks affect a plasma gun, its still the gunslinger or rifleman perk depending on if the weapon has a pistol grip or a rifle stock.

Yes, the launcher is affected by both, sadly cant confirm on the fatman.

Ok thanks. I was curios because I gave the cryo gun a rifle stock and it wasn't effected by rifleman, I assume because of the continuous fire thing which would put it under commando instead.

Or commando, still, its not affected by the heavy weapons perk at least, thats a given.
