Issue: #20
THE FINAL ISSUE OF GHOSTBUSTERS! Mass Hysteria comes to an end and the Ghostbusters discover the price of driving Tiamat from the city, county, and state of New York! But just because the Big Bad is beaten, it doesn't mean psychokinetic shenanigans are on the wane -- there's always another job on deck for the boys (and girls!) in grey! Don't miss the bombastically chaotic conclusion to IDW's ghoul...
