Great news for Magicka fans, a brand new mode which actually encourages killing other players will be added to the game this month. As someone who personally was unable to cast a single spell without either killing my teammates in some form or another, this is pretty exciting. It means that, at the very least, I'll do pretty well.
Four players will be able to toss down spells against one another in enclosed arenas, which feature their own additional perils such as cliffs, spikes, or an ice lake which can easily be broken apart. Hit the video below for the full E3 trailer, which doesn't give any additional information as much as it shows a small sampling of the chaos that can go on when players target one another deliberately.
