Salvation is a prequel to the film of the same name. The game begins with the robotic army of Skynet crushing an assault force sent by the Human Resistance. The human commanders order a hasty retreat but John Connor, a foot soldier, decides to stay behind to rescue a few Resistance members stranded behind enemy lines. This mission turns out to be the entire game. The mission itself isn't as important as Connor's personal development; the story shows him become a leader and regain hope in humanity's future.
