Code-named Puzzle Quest 1.5, the expansion contains four new Hero professions--Bard, Rogue, Ranger, and Warlock--along over 25 new quests, complete with new monsters and bosses, 50 new spells, and 40 new items.

To determine the expansion's official name, D3PA and Infinite Interactive are holding a contest for user-submitted suggestions. The contest, located at puzzle-quest.com, begins today at noon PDT and ends at noon PDT on March 21, with the results set to be announced on April 2.

The next full-fledged entry in the Puzzle Quest series, titled Puzzle Quest: Galactrix, is due out this fall on PC, Xbox Live Arcade, and Nintendo DS.
