DeathSpank: Thongs of Virtue has been updated with one additional achievement for an extra 15 Gamerscore from one of today's pieces of launch day DLC, the Snowy Mountain Dungeon. Currently free (240 Microsoft Points starting next Thursday), the content was supposedly only going to be gratis for those who purchased the game, though it is currently available without cost to everyone, so grab that opportunity while it lasts.

"Be alert brave hero! A freezing yet terrifying dungeon has opened up in the Snowy Mountains! Horrible enemies of ice, flesh and terror await DeathSpank in this, the greatest expansion of all time!"

 Frozen Justice  15
Kill the Taking Tree 

While you're at it, grab the free side-kick Tankko the Warrior, which will be available for 80 Microsoft Points after the free period runs out.

"A new warrior is ready to join the battle for Justice! Tankko the warrior is half-man, half-monster, all awesome! Tankko inspires fear in enemies and slight discomfort among friends." 

Note: It appears these are not available for queueing online, but you can find them through the dashboard as usual.

And of course if you plan on playing any of this content, you'll need the game itself, currently available for 1200 Microsoft Points. Or, go ahead and wait for that Deal of the Week that may never come,  ya cheapskate!

"Join DeathSpank, in his all new adventure! Fight through war-torn battlefields, tame the violent High Plains and sail your own pirate ship through the savage seas. DeathSpank will vanquish all-new evils, help all-new downtrodden, and dispense justice as only he can. Wield exciting new weapons, slay unbelievable new creatures and get to the bottom of the Thongs of Virtue. The downtrodden cry for justice and DeathSpank will save them or kill them trying."
