Paradox Interactive announces new details about Magicka, outlining features in the upcoming action/adventure based on Norse mythology. There's also a new gameplay trailer with a humorous take on the game and its conventions, starting with: "Once upon a time in a generic fantasy world." There's also a video interview talking about the game with Johan Pilestedt, CEO and Game Director at Arrowhead Game Studios. "The most important key feature is the dynamic spellcasting system where you can combine spells freely," he says. "For example, combining two elements, like fire and water creates steam. And if you then combine that steam with earth you create an earth projectile which, when it hits something, explodes in a steam cloud." The HD version of the trailer is embedded below.
