This is my imagining of Ada Wong, with (no surprise) longer hair, and a slightly modified version of her Resident Evil 6 outfit. I missed her dress from RE4, so I changed her black leather pants, to a black dress. I think it gives her a bit of a undercover business woman type feel.
I also did not give her her bow, as I imagine her again being more covert in this mission, so she has only some concealed knives, and portable grapple hook, at her disposal. Her grapple hook can be used in combat, in conjunction with her knives and hand-to-hand abilities, but overall, I envision much more of an infiltrate, avoid fighting, and sneak around enemies approach to gameplay.
