But it says it requires a 3rd party dl and account, so the game may have to go through steam anyway, I am not sure.

You get an extra Hat, sword and staff, as well as a new spell for buying through steam before Jan 31. Wizards Survival Kit DLC its called.


Seriously, try the demo out, its hilarious fun even on your own. The demo can also be used to play 4 player local Multiplayer. 1 keyboard, and 3 Xbox 360 controllers.
