Games Like Mercury Fallen

Awaken. Rebuild. Explore.

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.

Mercury Fallen is a self-paced sci-fi colony management experience with a focus on exploration, expansion, and story-driven progression. Deconstruct the remnants of an abandoned facility, construct new rooms, conduct research, and grow your colony both underground and across the planet’s surface.

Tear down the ruins, scavenge resources, and transform the underground into a thriving colony. Design essential rooms, power systems, and infrastructure to support your growing population.

Unlock advanced technology, craft vital upgrades, and send colonists on daring expeditions to uncover alien artifacts, lost technology, and the secrets buried beneath the planet’s surface.

Expand beyond the underground with surface expeditions and resource extraction.

Every colonist has a story. Some will thrive, others will struggle—but they all rely on you. Keep them housed, happy, and well-fed while managing their quirks, relationships, and unexpected disasters. As your colony grows, expand your workforce with clones and automated robots to optimize daily operations.
