And it's interesting that this time Ada is a pure villain. Right until now she was always staying somewhere between the dark side and the light side, but this time we see her infecting Chris' men. It will be a tough mission for Leon.
For what it's worth, I think Resident Evil 6 is going to be a tremendously more rewarding experience than Resident Evil 5 was. At least this time they're going to give us a combination of genres, survival horror and action.
