I think calling a trailer, which is a kind of montage, a montage trailer kind of does disservice to the idea of a montage, as we typically expect it edited into a more traditionally continuous work, but fine.
The ballad is fun. So too is the Smash Bros. nod towards a new game mode coming when Magicka: Wizard Wars gets out of its year of Early Access and officially launches on April 28. It's free. And pretty fun.
Or wait for more traditional series co-op fun when Magicka 2 launches in May.
