Ah. Neat.
As for fungal infestations, yeah. Fire’s the first step. Light those fungal ground on fire. Sometimes a single lighter would suffice, but sometimes you might need a little extra. Now if you got a mini-flamethrower CBM, two hits on one fungal square should be enough, unless it’s raining.
As for the fungaloids. Well, kill fungaloids in the way you wanna kill them. Spore clouds could be a bit annoying since sometimes you miss. Nail gun works since ammo can be plentiful. If you have the chain lightning CBM, then killing the clouds can be a bit faster.[/quote]
Chain Lightning is EASILY the best way to go - kill a few fungaloids, zap the area to get rid of the spores. Lather, rinse, repeat.
Unfortunately, short of multiple mini-nukes, a large fungal infestation is going to grow faster than any one character can kill it.
