Konami plans to formally announce a downloadable PS3 and Xbox 360 game based on Adult Swim's humorous heavy metal animated series Metalocalypse at this week's San Diego Comic-Con

Show creator Brendon Small is working with Konami to produce Metalocalypse: Dethgame. I wonder how involved Titmouse, the animation studio behind the show, are in the project, considering that it launched a game development branch (Doctor Zomba, Seven Haunted Seas) earlier this year.

The game will feature music from the show's fictional heavy metal band Dethklok but will not center on the cartoon's stars. Instead, players will follow a group of roadies fighting in service to the band. Metalocalypse: Dethgame. Apparently, there were difficulties with adapting Dethklok to a video game setting.

“The first idea was we make the band merciless and murderous but that doesn’t work on the show,” said Small, according to a report from the Wall Street Journal. "Our show is really about five narcissistic super-celebrities who can’t open the door by themselves."

The Metalocalypse creator also commented on the rising popularity of heavy metal video games, what with EA planning to release Brutal Legend this year. "If you’re an investor in some genre of music, I’d say metal is a good bet," he said.
