Zeke and Julie, our intrepid teenagers, visit the Ghosts and Ghouls exhibit at the city library, where they find an old treasure chest containing an ancient spirit book. Naturally, they cannot resist reading it. Suddenly, a horrific snaggle-toothed spirit emerges. Now, this snarling phantom and his dastardly minions are infesting Metropolis and slithering their way into the history books, where they plan to rewrite history with their spooky ways. Only you have the power to go back in time to de-spook an encyclopedia of zombified historic dudes.

Terminate, with prejudice, using crossbows, ping-pong ball machine guns, Martian "Heatseeker" guns, and more. Vaporize garbage can ghosts and ninja spirits, rescue bug-eyed librarians and wigged-out pirates, dodge flying books and adolescent-eating plants! Only our two heroes have the power to get the mighty beastly spirit back into his book and stop the madness. Ghoul Patrol to the rescue!
