[Update: The DLC is actually called 'Edie's Second Squad Challenge', and will feature a few more standard affair missions. Some of the early 2Ch.net posts called it the 'Battle Challenge' aspect, which is what led us to believe it may be an online component. It's actually a challenge mode for the various unit battle types, like spying on an enemy without being seen.]
Valkyria Chronicles has lived the ultimate underdog tale. After somewhat subdued sales in the US, the title has sprung back to life over the course of the past month. Sales surged 400% in the wake of the release of 3 DLC packages and a temporary price cut.
It seems like the little engine that could isn't done chugging yet! New DLC has been announced for Valkyria Chronicles in the latest issue of Famitsu. Details are still sketchy, but the DLC is called 'Battle Challenge'! Is an online competitive multiplayer coming to the game? Seems likely!
We've contacted Sega's US branch for confirmation of a US release as well.
