Koening

You're a soldier, your primary job is to keep the enemy out of your territory. You mostly sit in the same room, staring at a monitor, watching the cameras.

One day, you see Colonel Koening—your enemy—approaching your base. He was notorious for his brutal murders, not only of soldiers but also of ordinary civilians. He didn't care whether you were a man, a woman, or a child. He had a goal, and he would carry it out to the last. And now his goal was to capture your base.
