Paradox North's team-based, player-versus-player game Magicka: Wizard Wars has shown itself off previously, but never in motion like this. The real-time spellcasting of Magicka was already deadly in so-called "cooperative" play, so one can imagine how disastrous things can get here.
If you've got the skills necessary to cast that spell you actually intended to cast or are otherwise interested in checking out Wizard Wars, Paradox has opened up alpha sign-ups on this website. The more of you that register, the better rewards we all get.
