Dead Rising 2: Case Zero surpasses 600K download mark

Dead Rising 2: Case Zero, the "most dynamic sales weapon" publisher Capcom has ever had, has surpassed the 600,000-downloaded mark. The $5 XBLA-exclusive sold another 100,000 units in October, topping the Xbox Live Arcade sales chart and apparently making it the "fastest selling" XBLA game of the year.

The full-bodied demo/prequel to Dead Rising 2 has been an incredible success, selling nearly a half million units in its first two weeks back in early September. As for Case Zero's sales impact on the full game, it certainly didn't hurt the sequel, as Capcom announced in late October it had shipped over 2 million units of the game to retailers.
