I just found the perfect weapon against the Zerg.

LOL @ "Borg/Zerg can adapt to anything." When will this myth die?

I didn't say they could adapt to everything, but they can adapt to this fungi.

Infested terrans are generally "brain dead".

well they talk.

Meaning they're not completely brain dead, they or the thing controlling them can access the language sector of their brain.

In that video, it says the cordyceps infected ants are carried far away.
Well the zerg would probably do that as well, and we all know how fast a ling can run, if a zerg is infected, just carry it away. Then kill it. the rest will be safe.

I'm using the lore source StarCraft: Hybrid. It doesn't take a lot of intelligence to talk anyway. Given they already had a language center of the brain, if it only partialy "rotted" it can still be partially functional. However, non-brain dead infested terrans like Stukov, Kerrigan, Morik and Stewart are a major plot point post-Brood War.
