As if Magicka didn't already suffer enough magical 'friendly fire' incidents, developer Arrowhead and publisher Paradox have announced that wizard-on-wizard violence will be formalised on June 21 when the PvP mode launches for free.

Along with classic Deathmatch, which players are apparently quite capable of emulating for themselves at the moment anyway, there'll be another two modes for duelling wizards. Brawl will give players or teams a limited number of lives for them to fritter away until there's only one survivor. Kreitor mode, inspired by an eponymous fan, will see new Magicks unlocking at intervals, so the match changes over time as wizards get new toys to play with.

Launching alongside the free PvP mode will be paid downloadable content with new combat arenas and robes. If you've ever wondered what would have happened if Captain Kirk and Spock were wizards when they duelled in the Star Trek episode 'Amok Time,' you'll want to snap up the 'Vulcanus' map, which bears more than a passing similarity to that famous arena.

Pricing has not yet been announced for the paid DLC, but for reference the last Magicka map pack cost $1.99 and item packs have cost 99¢.
