Mercury Fallen

A sci-fi colony management sim with a focus on exploration, expansion, and survival. Rebuild your underground facility, manage colonists and robots, and uncover the mysteries of an alien world light-years from Earth. Dig deep, expand across the surface, and shape your new home.

After a long journey to a distant planet, your colonists were supposed to wake up and begin building their new home. But something went wrong. Their stasis capsules malfunctioned, and when they finally awakened, the underground facility they were meant to inhabit has fallen into ruin.

Now, it's up to you to restore the base, manage resources, and expand across the planet’s surface—all while uncovering the secrets of this alien world and ensuring your colony thrives.
