About Megaton Rainfall
Megaton Rainfall puts you in the shoes of a lone superhero battling a worldwide alien invasion. The game is presented from a first‑person view, letting you chase massive alien devices across a planet the size of Earth.
You can fly at supersonic speeds, break the sound barrier, and even leave the atmosphere to circle the globe in seconds. While you unleash lethal energy blasts on alien threats, you must also avoid harming civilians, as missed shots can collapse buildings.
