I am Walker, a 32-year-old special agent of the US Intelligence Agency. I was ordered to sneak into the Red Army City to rescue the missing US special agent David. The Russian raid was six hours ahead of schedule, the city fell and the defense collapsed. I was alone, without support or response, and had to find the target within five hours. Time is running out, enemies are pressing in, and every second is deadly. Disguising, sneaking, and fighting, I walked through the edge of hell. One wrong step and it's a dead end.
