Her name is Sophia. A deep childhood friend of yours, she suddenly leaved your Highschool after you both graduated highschool. Lacking direction and a crucial part of yourself (in the form of her), you enlisted in the military and became a SAS (Special Air Service) operator to gain a purpose.

You and your SAS colleagues answer a call of a terrorist atack in London, a really important city to the United Kingdom. Rife with civilians and important people.

You find yourself looking out of a window dressed as a civilian, scouting for something strange...when you see her, in full tactical gear and body armor, with a modded out H&K assault rifle and with her colleagues of the CTSFO.
