[Update: James Gunn has clarified his role a bit, and it appears he was on board with the game from its inception.
"I was involved with crafting the story, and helping to create the characters, and writing the dialogue," he writes, "This was not only stuff that affects the English translation of the game, but the heart of the game itself -- so yes, the Japanese version has my imprint on it as well."
He also drops a little tease, adding "many of the the folks who you see regularly in my films and other projects also have roles to play in Lollipop Chainsaw." Gunn has worked with a wide variety of actors and actresses, so who could make an appearance is anyone's guess.]
We got a bit of great news today when Warner Bros. announced that it would be partnering with Kadokawa Games to bring Grasshopper Manufacturers' Lollipop Chainsaw to the world outside of Asia.
