Microsoft - Nine Parchments

NINE PARCHMENTS is a co-operative blast 'em up game of magical mayhem from Frozenbyte! Runaway apprentice wizards seize the opportunity to complete their spellbooks by going after the lost Nine Parchments. As the would-be wizards rapidly acquire powerful new spells without learning proper safety measures, it's natural their hasty progress results in plenty of deadly accidents...

Nine Parchments combines real-time spell-shooting action with RPG elements - level up your character and collect magical loot, filling your wardrobe with a myriad of wizard hats and powerful staves.
