An upcoming title update for Resident Evil 6 will add/unlock some free content for the game, a new Capcom Unity post reveals. The big one for many will be the unlocking of Ada Wong's campaign for one and all, meaning you'll no longer have to complete the game's other three campaigns in order to play through Ada's adventure.
The content update will also turn Ada's campaign into a co-op outing, though there's no word on who her partner will be. Given that the fourth, unlockable campaign was designed as a solo experience, it's hard to say how the change might affect the experience. More co-op is hardly a bad thing though. Also being added is a new No Hope difficulty setting for those players who are gluttons for punishment.
There's no final word yet on when this update will be arriving; Capcom promises that fans can expect to see it "soon."
