You're the last one on his team that's still alive

Chris and his team were sent out on a mission to take care of some BOWs a bioterrorist organization were developing. The mission was supposed to be easy, according to the higher ups, but they were wrong. Everyone walked right into a trap. Only you and Chris Redfield are left alive.

I made up some guy named Xavier to be some bioterrorist guy, but honestly, you can edit the name to be anything you want. I wasn’t sure if I wanted to put down an organization like Umbrella, or II Veltro.
