UPDATE: Parts 3 and 4 are not on Newgrounds but can be played at MillieMegavolte.com.
After being chased into hiding by the Ohnmouthe Guard, Millie and Lance stumble upon the grungy pit of Ogg'khar the ogre. As it turns out, the demons they were after weren't the only ones--there are more of them deep within the Depths doing who knows what. Play as either Millie Megavolte or Lance LeTourre and put a stop to whatever they're doing.
NOTE: Some things in the game may act weird upon resizing.
