Call of Duty: Ghosts2013

Elias T. Walker:
[In the introduction of "The Hunted"] There are ancient tribes, deep in the Amazon, who have perfected the art of torture over hundreds of years. The Federation embraced this heritage, enhancing it with more sophisticated methods. They kept Rorke in a hole for months... feeding him foods mixed with the poisons of exotic plants. As they broke down his body, they went to work on his mind. When his mind broke, they went to work on his soul. They rebuilt what was left, twisting him to their purposes. The process was excruciating and exacting. Rorke was their Ghost now. The perfect weapon to use against us.
