Avenged Sevenfold have posted an update regarding their upcoming "Hail to the King" animated series, a collaboration with Metalocalypse producer Jon Schnepp and Machinima. Apart from unveiling a 45-second teaser, singer M. Shadows personally addressed the crowd through Facebook, revealing that the series comes as a backstory of the band's upcoming "Hail to the King: Deathbat" video game. Kicking off by thanking fans for great support on recent European dates, Shadows focused on the animated series. "It's funny stuff and it was an honor to work with [Schnepp]," the vocalist noted. "We hope it gives you something entertaining to watch over your Holiday break. The series also plays as a backstory to our mobile game 'Hail to the King: Deathbat.' We felt this was the best way to tell the story and give you all an idea about the type of game we are creating." Further discussing the game, Shadows described the decision to delve into the gaming world as a logical choice in today's time of smartphones and tablets. "So we came up with the idea of turning some of our songs and art work into a living, breathing, evil world," he explained. "We wanted to bring the story of the Deathbat to life and allow you to control its destiny. While the game stands on its own in terms of the story and game play, we still wanted to add in some extras for our fans." The vocalist then focused on some of the game's exclusive features, confirming seven new songs will be available for players to unlock. "In the game you can unlock 16 pieces of never seen before artwork from all of our albums. There will also be 7 new Cam Rackam paintings available in the game. We also recorded 7 new songs. Now these aren't metal songs, they are theme songs for each level and are done in an old school video game fashion with a new school twist. There will also be reimagined versions of older songs." As for the game's release date, "Deathbat" is currently in the beta process and should see the light of day in early 2014. "Remember, the game and series go hand in hand," Shadows concluded. "The animated series tells the story "before" the game takes place. When the series ends, the game picks up." Check out the trailer below and let us know what you think in the comments.
