Cities: Skylines has always been a game that takes some different approaches to city builder gameplay. The base game explored how a city's geography can influence the development of the city, and also put a particular emphasis on designing efficient transit infrastructure by allowing the player incredible freedom to construct your own roads, highways, and interchanges, rather than relying on prefab ramps and over/under passes. None of these concepts were new to city builders, but Skylines added nuance to them and made them much more active elements of gameplay.
Its newest expansion DLC, Natural Disasters, follows suit. This is a very difficult expansion to review because its content - by its very nature - is random and unpredictable. Natural disasters aren't new to city builders. Disasters were a popular component of the old SimCity games, as many players enjoyed building up their beautiful metropolises only to unleash earthquakes, tornadoes, meteor impacts, and even alien invasions and dinosaur attacks and watch it all burn. Now Skylines has support for this fan-favorite SimCity feature, but it takes this commonplace feature in some new and interesting directions.
Installing early warning and detection systems will give you advance notice when a disaster is imminent.
Most notably, Cities: Skylines' take on disasters puts emphasis on preparation for disasters, rather than on the chaos of the disaster itself and the clean-up in its aftermath. Like with its SimCity forebears, disasters are something that you can toggle on or off in the game's menu, and you can also adjust their frequency. When enabled, you'll encounter disasters of various flavors ranging from forest fires to lightning strikes, to tsunami and meteor impacts. You'll have to make sure that your city is protected by preventative measures, and that it's protected against these eventualities.
Early-warning systems like firewatch towers, weather radar, and space telescopes can warn you about forest fires, storms or tornadoes, or even incoming meteors (respectively), and can mean the difference between your citizens having enough time to evacuate, or half your population being buried under rubble. You'll need evacuation shelters for you citizens to escape to, and each shelter needs to built long enough in advance for it to be stocked with supplies of food, water, and other essentials (which must be pulled from your city's economy or imported). And lastly, you'll need radio towers to warn your citizens to get to their designated shelters.
Building emergency shelters, stocking them with supplies, and planning evacuation routes will protect your citizens.
You can also create planned evacuation routes similar to bus routes that will pick up residents and take them to a shelter. I had some trouble getting these routes to work properly though. The fact that the buses are dispatched when an evacuation is activated means that they often create a log jam on your roads as they all funnel out of the shelter. I also had issues with the buses apparently not picking up people who were at more distant stops on the route, since the areas along the route that were far from the shelter never managed to evacuate. Maybe there's some trick to getting these routes to work properly that I just haven't found yet. But this does highlight one problem with the expansion: its new systems are not very well documented or explained...
