The Brainwash mod was a weapon modification. Any enemy struck by a weapon with the Brainwash Mod attacked other enemies, but it did not make them lose health themselves like the Infector. It caused the victim to see its allies as an angry horde of political talk show hosts.
The mod worked by filling each ammo round with a potent drug known as Friendium Paranoiathol.
