Criss started off as a medic in England, but her combat skills earned her so much respect that she was dispatched to the Counter-Terrorist forces. Everything about her is a big mystery, but there are rumors that connect her to the Rex Research Institute.
In the Official Counter Strike Online comic: Side of Shot, it is revealed that Criss worked for the Rex Research Institute by specifically performing tests on live human experiment subjects. However, these tests lead to the deaths of those individuals. She later encountered Jennifer held captive.
As Criss escaped the research facility from an internal outbreak of zombies, she managed to collect a blood sample which most likely contains the zombie transforming virus.
