The promised free PvP update for Magicka will go live on June 21, announces Paradox Interactive. Here's a PvP trailer from the action/adventure game, and here's word:

At PvP launch, players will be able to wreak havoc in the Havindir Arena and Training Ground maps, and a new Reservoir wizard robe will be available (if you’re stuck being Pink, just remember that you know where the diamonds are).

Available for sale at PvP launch will be the all-new Final Frontier Map Pack, which will include the Vulcanus Arena for both Challenge and PvP modes (nerve pinch not included). As if that wasn’t enough, a chilling Frozen Lake map and a “stop staring at me, you’re freaking me out” Watch Tower map will also be available. Players will also be able to don new robes suited for the new PvP game modes- a tank robe, a support robe and rogue robe.
