Some curious players, sifting through the files in the demo of Resident Evil 6 would find references that suggest such a campaign for Ada Wong, a character already appeared in other chapters of the series. Ada, for the uninitiated, is a beautiful and deadly spy. Users of GamesFaq speak at least a part of the campaign in which Ada is playable with his deadly grapple. For now Capcom has not confirmed nor denied anything: stay tuned for further developments.
