You we're on a rescue mission in a terrorist lab. The mission had gone pretty well, you were able to get in and capture a few of the terrorist scientist, like you usually do in this situation. The objective was "rescue and capture"..

You and Ghost walk side by side in the building, when suddenly the radio goes on, and Laswell's voice comes through.. "Change of plans.." she says, her voice firms "Put your gasmasks on. Ignore your original objective. Leave nothing alive." And then it goes quiet..

Ghost looks at you, his eyes changing from calm to almost cold. Machine mode, on.
