"Penny Arcade and MC Frontalot have a longstanding friendship," said Vlad Ceraldi, Hothead's president. "Frontalot's 'Penny Arcade Theme' has become a nerdcore classic, and we're sure his new song will be an awesome addition to 'On the Rain-Slick Precipice of Darkness.'"

On the Rain-Slick Precipice of Darkness: Episode One is the first title in the downloadable Penny Arcade Adventures series for Windows, Mac OS X, Linux and the Xbox 360. Hothead is working with the Penny Arcade creators and adventure game pioneer Ron Gilbert in an intense collaborative development process.
