If you plan on getting DeathSpank: Thongs of Virtue in the relatively near future, you might as well make the transaction this week. Those who purchase the game on PlayStation Network by September 27 or grab the Xbox LIVE Arcade version by September 28 will get some free stuff.
To be more specific, the Snowy Mountain Dungeon and Sidekick Tankko downloadable content are your rewards. After the aforementioned dates, these digital items will cost $2.99 and $0.99, respectively.
To be frank, I thought the move to push out a sequel so soon was strange, but this — kinda sorta having premium add-ons right at launch — is perhaps even stranger.
