For a long time, a gang of daring robbers terrified the city's wealthy citizens, plundering houses and banks. Then word came that they planned to break into the central museum to steal a royal crown set with a huge ruby. The building has been surrounded, but the robbers refuse to surrender.
All entrances and exits are sealed, and you, as the police sniper, have your orders: stop the robbers inside. Watch the windows and rooms through your scope, find each gang member and take them out before they can escape with the crown. Take your time to aim, because a missed shot alerts the gang.
