It's some kind of an old bundle called "Magicka Complete Pack 2011". So... yeah, not exactly complete anymore, but a bundle is a bundle.

Aside from Magicka itself it includes:
Magicka: Vietnam,
Magicka: Wizard's Survival Kit,
Magicka: Nippon,
Magicka: Marshlands,
Magicka: Final Frontier,
Magicka: The Watchtower,
Magicka: Frozen Lake.

As you can see, those DLCs are more expensive than a base game, so feel free to enter simply to get some of them - although if you are really, really interested only in that tiny 0,99 piece, then kindly consider offering Magicka giveaway on your own after winning. Not like I am going to haunt you if you don't, but... (ominous voice) your conscience will.
