Have you already fulfilled the titular imperative delivered unto the player in Robot Entertainment's XBLA strategy-action title Orcs Must Die? The joke's on you: There's always more Orcs. This time, they come in the form of the "Lost Adventures" DLC pack -- an expansion which came to PC last month, and will bring its five new fortresses, two enemies and additional collectible skulls to the XBLA version of the title sometime in December.

Of course, the 400 Microsoft Points ($5) you drop on this bad boy will also net you a handful of new tools, like the energy-restoring Mana Well, the health-draining Vampiric Gauntlets and the Shock Zapper, which both shocks and zaps. We know, we always assumed those two were synonyms as well. We guess we'll have to see the thing in action before we understand the subtle differences.
