Try a little Brimstone to bring out the demon in you. Gabby thought the brimstone drug was destroyed. However, now a multitude of demons plague New York, and from the look of their scaly skin, the drug has taken hold of the Big Apple. When Gabby finally uncovers the mastermind behind it all, she realizes this battle won't be easily won. Faust is unlike any demon Gabby has seen before, capable of possessing multiple entities at once; he’s even manipulated a corporation of vampires into spreading their own version of brimstone. If Gabby and the Van Helsing Organization don't put an end to Faust's plan, it'll soon be Hell on Earth.
