You may not have guessed it, from how many Arcane Novas and Steam Lightning Storms were cast in the direction of other players, but wacky action-RPG Magicka was originally a co-op game. PvP arenas were added free DLC to formalise the wizard-on-wizard violence, and the next game goes even further. Announced today by publisher Paradox, Magicka: Wizard Wars is a purely PvP affair, boasting 4v4 magic man action.

Magicka, if you were unfortunate or foolish enough to miss the original, has the most wonderful and chaotic spellcasting system. You combine up to five of the eight elements--from Earth and Life to Fire and Shield--into a single spell. This can be cast on yourself, on your weapon to imbue it with power, or tossed around in a number of ways. With so many combinations, you can get cast unusual things like a Chilly Exploding Electric Ice Wall or Healing Mines. Which deal as much damage or healing to friends as to enemies. Things go wrong, quickly, often, and unexpectedly.

This zany system will of course remain in Wizard Wars, which Paradox says will result in "short rounds and unpredictable strategies." More importantly, you'll have a persistent customizable wizard, with hundreds of items to choose from. No word yet on when it'll launch.

Magicka creator Arrowhead is not making Wizard Wars, but rather Paradox's own Paradox North studio. Arrowhead's most recent work was multiplayer side-on shooter The Showdown Effect.
