No revenue estimate for the App Store: Apple publishes no install counts, and its star-rating counts don't calibrate to sales the way Steam's written reviews do. Reviews and prices only.
UFOs are no longer just the subject of conspiracy theories. After a series of unexplained alien encounters, the world is rapidly spiraling out of control. Cities are in panic, governments are blaming each other, scientists are trying to decode the signals, and humanity is being pushed toward extinction under the shadow of an extraterrestrial invasion. Your mission is not to rule the world; it is to stop it from falling apart. Use your resources wisely, defend cities, keep public morale alive, manage diplomatic crises, and stop the invasion from spreading. Sometimes saving one city will mean putting another region at risk. Sometimes a scientific breakthrough will force you to sacrifice defense. And sometimes, the right decision will be the most ruthless one. Every day brings a new crisis. Every choice changes the fate of the world.
