Welcome to a new kind of city builder. Urban sprawl is enveloping the planet, and as nature, it's your job to fight back! Use your arsenal of natural disasters to grind skyscrapers into dust and beat civilization into submission. Replace towers with trees to restore the environment and generate energy to fuel your attacks. Upgrade your powers to take on greater challenges as cities grow and defend themselves. Conquer dozens of hand-crafted stages across five distinct regions, culminating in epic showdowns against mighty megastructures and iconic real-world cities. Master unique scenarios against settlements that expand and adapt to your assault. Obstacles like meteor-intercepting missiles and wildfire-fighting water tankers will require careful consideration - or an overwhelming show of force - to overcome. But you have more in your corner than just raw strength. Combine disasters to overcome obstacles and outmaneuver crafty defenses. Use the environment to your advantage, cratering the ground to deny your enemy territory or manipulating the seas to trigger massive tsunamis. And that's just the beginning! Annihilate as many buildings as possible and unleash awesome setpiece disasters in Arcade Mode. Craft (and crush) your own megalopolis in the free-wheeling Sandbox Mode. And tackle an endless cast of procedurally-generated cities with the Daily Challenge! In this game, you’re not a city builder. You’re a force of nature. An Unnatural Disaster!
