Resistance: Fall of Man
Captain Rachel Parker is the daughter of a three-star general who served in the British Military. Because of this, she was often moved around the country and never really had anywhere that she could call home. This also caused her mother to leave when she was six, due to the strain of always being on the move. This ultimately force Parker to become exceedingly close to her father, which meant she also wanted to join the Military to be closer to him. He instead tried to move her towards getting a University degree though, as he feared for her safety.
However, after excelling at Oxford University, her father could no longer ignore what she had to offer and gave her a position in the Intelligence branch of the British Military. He needed someone he could trust due to the impending threat of the Chimeran forces, and he found that in his daughter.
After the Chimera invaded, her father was unfortunately killed trying to get Parker to safety, and it was because of this that she vowed to fight on and rid England of the Chimera. Her knack of making the best out of any given situation had never failed her and when she comes across Nathan Hale she finds herself using her tactical nous more and more in an effort to drive the Chimera away.
