In Emergency 3, you control a city's first responders -- EMTs, fire and rescue services, police, and so on--responding to emergencies. In twenty missions, you have to deal with a wide variety of them, from raging fires to explosions, derailed trains carrying dangerous chemicals, etc. There's also a 'sandbox' mode with randomly-generated emergencies, so once you've completed the missions, you can continue to play indefinitely, if you like. It's a real-time strategy game, in a sense, but your objective is saving lives, rather than conquering enemies.
