According to the Kickstarter description, "Grimoire is a multiplayer mage FPS with MOBA-style abilities that puts the player in control of devastating magic." Players can fight from first- or third-person views and take on the role of one of 10 wizard classes.
Grimoire's been in development for a year, is currently being voted for on Steam Greenlight, and even has a combat preview demo that you can download and try right now. The makers said that the game's had "practically no budget" up this point, which is why they're looking to raise $42,000 to improve what's already been made. The soundtrack is being composed by Pirates of the Caribbean Online vet Marcus Zuhr.
