Fight your way through the flames and keep the neighborhood safe. Use your firetruck to put out fires, then transport the wounded to the hospital. After disaster's been averted, bring in the construction crew to patch up the building! You'll get more vehicles and responsibilities as you progress through the game. Keep the neighborhood safe and reach the goal score to complete a level!
