Yes! Ada Wong has been confirmed to have her own campaign.
She is a mysterious character in a mysterious game. And is one of only a handful of side characters that I actually care about, ever since she came onto the franchise back in Resident Evil 2.
She will not only be a side character in the upcoming Resident Evil6, but she will be the main character.
She did have the spotlight back in Resident Evil 4, but it did need refining as it really gave the impression that they had some spare code for the game and replaced Leon with Ada.
So hopefully this is the real deal, a full immersive campaign, that will give away a few more details of this complex character.
