A list of folders included in the Resident Evil 6 demo from the Xbox 360 demo have popped up on GameFAQs, showing a campaign menu option for Ada Wong as well as her hookshot. She is set to appear during the Leon, Chris and Jake campaigns as an NPC. The list also states Resident Evil 5’s Sheva Alomar will be included as well. Ada was rumored for the game as far back as January, but still, take all this as a rumor until Capcom confirms it. Thanks, OXM.
