The boys and girls at CAPCOM are at it again… moping up yet another PR issue…
Recently it was discovered, surprisingly to no one, that DLC was found on the disc of the retail version of Resident Evil 6. Capcom, no stranger to this controversy, had a quick explanation. Refuting the earlier claim that there was no DLC on the disc to begin with, contrasting the claims of those who found it.
Capcom claims the on disc DLC is in fact “incomplete” (see Mass Effect 3) DLC that will be offered for free. However, a download will be required to access the on disc DLC, which includes a new co-op and stand alone difficulty modes, is the only on disc DLC and that no paid DLC has anything on the retail discs.
An update is to arrive “soon”.
