RIOT
Sims riot for many reasons. Property is put at risk by fires, and injuries can abound. Traffic can become a mess if the riot goes on for too long.
A line on your city map extends from you to the riot. Additional riots will show as icons on your city map.
There's a riot goin' on.
By the time you arrive, the riot has already developed. Rioters are always on the street, throwing debris and causing mischief. There can be several dozen of them.
To receive full bonus and points, you must use your megaphone and spotlight first, then your water, and then your tear gas. If you use your tools out of this order, you may end the riot quickly, but you will lose points.
Your spotlight and megaphone can discourage new rioters on the fringe and break up small groups. Your bucket or water cannon will discourage and break up larger groups closer to the center. Use tear gas to immobilize the largest groups at the center of the riot.
Strategically placed police and fire trucks can contain and diffuse the riot, and ambulances can help treat injuries. When rioters leave the area, they cease to riot. When enough of them leave, the riot is over.
You receive incremental bonuses and points as you diffuse the riot. When the riot is over, take care of any secondary missions that the riot may have caused.
Riots can be common.
