Double Fine studios revealed to Gamespot
that a new DLC pack titled "Grubbins on Ice" will soon be arriving on XBLA.
The events in "Grubbins on Ice" pick up from shortly after the adventure in Costume Quest
concluded. The turn based combat from the core game returns, though new costumes are added this time around. The DLC is said to be slightly longer than an average level in the game which means that you can hopefully look forward to "Grubbins on Ice" extending gameplay to a total of 5 hours or so.
Double Fine is also taking this opportunity to release a patch which will tackle several issues with the game. The patch addresses the save system in Costume Quest
by allowing you to save at phone posts around the neighborhood. It will also adjust the speed of the dialogue text and allow you to pause during cutscenes.
No specific date was given for the new content, but it is currently slated for release sometime in December.
