I'd say greatly increase the area of effect, but keep the same damage, then i think it would be actually worth purchasing it. And yes, its very expensive, every time i see a firebug wielding it, he dies in 1-2 waves from the purchase. Hope TW does something about it
I was playing the game earlier, and bought the Husk Gun...hadn't tried it out in an actual game that wasn't me goofing off in solo...and I managed to survive 2 waves with it...I, in fact, wound up being the only player who made it through all 10 waves to the Patty alive...but I dumped it after that 2nd wave for the Flamethrower.
...it's just a better weapon. :\ Despite the fact I like the Husk Gun and find it fun, the Flamethrower is just much more effective.
...and also? the Patty took us all out. The jerk.
