Dubbed "The Sacrifice," the second game add-on for the horror game Left 4 Dead 2 serves as the prequel to "The Passing," and takes place from the L4D Survivors' perspective as they make their way South. In addition to advancing the story, "The Sacrifice" introduces a new style finale featuring "Sacrificial Gameplay" where players get to decide who will give their life so the others may live.
