It's kind of hard for me to believe it, but Magicka (the quirky, and hilarious, craft-your-own-spell RPG) turns two next week. Time certainly flies. To celebrate, Paradox is offering not only a free weekend for gamers, but also free DLC for players who already own the game. During this weekend, you'll be able to download and play the game for absolutely free. It's currently available on Steam, and the free play will extend until Sunday 1pm PDT. The game is also discounted down to $2.49 from $10 until Monday.
