The story

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.
