Resident Evil 6's on-disc DLC will be free of charge when it launches "soon" as a title update.
It will introduce No Hope difficulty mode, which Capcom describes as "super hard", plus a co-op partner for Ada's campaign.
Additionally, Ada's campaign will be available from the start of the game - currently players need to complete Jake, Leon and Chris campaigns to unlock it as a bonus.
Capcom said that DLC data stored on the game disc "is incomplete and requires the actual download to access".
After a backlash from consumers about paid on-disc DLC, Capcom said in May that it was in the process of "re-evaluating" how it delivers additional game content.
