and filmmaker Guillermo del Toro Novelization Hellboy II: The Golden Army (June 18, 2008, ) by Robert Greenberger is the official novelization of the film. Video game During its initial theatrical release in North America, a video game set within the Hellboy universe was released around the time that of the film entitled Hellboy: The Science of Evil for PlayStation 3, PlayStation Portable and Xbox 360, released on June 24 in North America and August 15 in Europe. Despite its close release date, promotion alongside the film and featuring voices of the same actors, the game is not a direct movie tie-in with the plot not being related to that of the film but instead follows an original story where Hellboy investigates Nazi operations in Romania under Herman von Klempt, an antagonist from the comics. Zinco epilogue Included as a special feature on the DVD is an animated comic that foreshadows the events of the next film. In the Zinco Epilogue, a group of men go into Rasputin's tomb and find Kroenen's body. After bringing Kroenen to a doctor along with instructions to revive him with an alchemical manual, Zinco and his party travel to an arctic cave with Zinco as the only survivor. Upon entering the cavern, Zinco opens a container he has with him containing the preserved head of Kroenen and attaches it to a giant robot. As soon as it is attached, the cyborg awakens and the spirit of Rasputin appears, stating that he has one more job for him. Post release Cancelled sequel and spin-offs Del Toro had expressed interest in a sequel, saying, "I think we would all come back to do a third Hellboy, if they can wait for me to get out of Middle-Earth, but we don't know. Ron may want to do it sooner, but I certainly know where we're going with the movie on the third one." On May 30, 2010, Guillermo del Toro dropped out of directing The Hobbit. In June 2010, Del Toro speculated that Hellboy III might happen after his next project, but said that the screenplay had yet to be written. On July 14, 2012, after being inspired by a recent Make-A-Wish function in which Ron Perlman appeared in full Hellboy makeup for a terminally ill boy, Del Toro stated, "I can say publicly that now we are together in trying [to do Hellboy 3]".
