I'm gonna assume she was 25ish in RE2 where she made her first appearance. If that was in 1998, 14 years passed between her debut and her latest appearance in RE6, which takes place in 2012, so she could be 39.
Anyway, if Ada is in her late 30s or early 40s, the devs made her look about half her age. Anyone notice this and thought it was unrealistic? lol
Lucy Liu is 44 and she still looks like she's young. There's plenty of people who look way younger than they are, Halle Berry, Angelina Jolie, Cameron Diaz. Maybe Ada just has a really rigorous skin routine.
One of the proud people that still plays Mirror's Edge to this day. Not changing my sig until DICE officially announces Mirror's Edge 2
