After getting back the President's daughter, Hunnigan didn't waste time to put Ren in another mission. Ren took the opportunity instead of explaining the situation about why he was there in Spain to Leon. Hunnigan didn't want him to know about it even the President didn't want him to know. Years past without one of them making contact with eachother, it was as if Ren disappeared of the face of the Earth. Leon had many emotions on why Ren just disappeared but he didn't get an answer. But this day where everything went wrong, the President turned into a Zombie, people getting killed from the blue smoke. The world is in turmoil. The C-Virus has spread to Epidemic Proportions. The Bioterror Threat looks to lead Humanity into a chilling end of days. When all the goodbyes have been said and all hope seems lost. One final struggle begins. Old faces show up and the only one behind it is..... Derek C. Simmons and Carla Radames (Project Ada).
