The mages of Magicka are headed to the online arena in a multiplayer-focused, four-on-four PVP battle game called Magicka: Wizard Wars. Paradox's announcement doesn't mention the genre explicitly, but the new game sounds like it falls under Multiplayer Online Battle Arena (MOBA).
In Magicka: Wizard Wars, two teams of four wizards duel to the death using Magicka's established spell-crafting system as the foundation for combat. The game is differentiated by "short battles, persistent character progression, and plenty of laughter."
Magicka: Wizard Wars is in development at Paradox North, a new studio in Stockholm under the banner of Paradox Interactive. The studio is composed of former DICE and Avalanche Studios talent, and led by executive vice president John Hargelid.
