I'm not exactly sure what the HHF would sound like, I think it would be more akin to an industrial heating torch (Meant to keep metals and fragile glass work hot.) (The Flamethrower from Natural Selection 2 has an appealing sound.)
Which I'm sure you can find some kind of sound for.
If I ever get back into this I'd like to improve the particle effects a bit, add a different on contact effect as well.
I always felt like it should be a concentrated beam of fire, which is why its got a cone shaped muzzle. (Although right now it just spews flames like a traditional flame thrower).
I mean its supposed to be able to burn through thick worm and scorpion skin, a more traditional flame thrower is supposed to be for clearing out hives (Or for killing off mite swarms and the such).
The Exo-Suit is actually supposed to have two versions of its flamer, an industrial shorter ranged focused version (Higher DPS, Lower Collateral spray, More efficient fuel usage), and the traditional napalm style flamer (Lower DPS, Burning DoT, wider cone/flame spread).
Of Course this is kind of how I imagined it, the HHF and anything I contributed is now Army's Baby and he has the right to turn it into whatever he wants to.
Also hey everybody how is it going?
