Last but not the least, let me introduce to you the Tsunami. It’s one of my personal favourites. A Tsunami disaster starts with a wave in the sea, outside the map area. That wave then travels towards the city. Tsunamis are greatly affected by the map topography. If there’s a line of mountains or steep hills between the sea and the city, the Tsunami might not do any damage in the city. Also valleys and other low areas can make the wave just stay and not be able to travel further. Tsunamis do the most damage on terrain that’s fairly even, when the huge wave can freely travel into the city.When the wave is in the city, things get interesting. Just like the Tornado picks up cars and other small things, the mighty Tsunami wave can take things with it. If the Tsunami is very mild, it might not do other damage than leave some excess water in your city. For this, there’s many options to handle it. You could add a canal in the affected area and allow the water to flow into it. You could landscape the area and add a pit where the water would flow, creating a little pond until the water evaporates. Because of the evaporation, you can also just wait and the problem will solve itself. Or you can build the brand new Pumping Service! The service sends out tank trucks that suck in water to fill their tanks and then return to the service building where the water is fed into the sewer system. If there’s a big flood, you might need an extra water outlet to handle the extra sewage in the system. All of these techniques also work with regular floods, so you can prepare better for landscaping accidents and other ways of water getting into your city.So the Pumping Service takes water away, but to make things more interesting, you can also build Fresh Water Outlets. They work like sewage outlets, except that they pump out excess fresh water in the system. This allows you to create ponds and even rivers. Or just fill out a meteor crater and give a disaster-stricken neighbourhood a new, lovely lake. The Fresh Water Outlet only pumps out water if it is on and there’s excess water produced. If everything the pumps and water towers produce is needed by buildings, the outlet will not let any water out.Another system that helps handle water are the Tank Reservoirs. They act as an extra water source when full if the city needs more water. This way you can have a small buffer for water, so if a pump fails or a water tower is destroyed, things can be fixed before the lack of water affects the citizens and businesses.If a severe Tsunami hits your city (or you delete the wrong dam, whoops!) buildings can get destroyed by water. Basically if the water rises higher than the building, the structures are lost. The normal warnings of buildings and roads flooded still exist, but now flooding can have a more powerful effect.I hope these development diaries have been as nice for you to read as they are for me to write! It’s not too long until Natural Disasters is released and I will admit I’m quite excited. The scenario editor adds a whole new game mode, a new way to play, and I’m looking forward to seeing all the wonderful, wild and weird scenarios people come up with. The disaster look and feel awesome, and they add much to the game when instead of just growing the city, you now have challenges to overcome. Of the new services, my absolute favourite is the Pumping Service. I always tend to spill some water somewhere in my city, and the service makes it so much easier to get rid of the mess!Anxiously awaiting release,Karoliina
