The player's primary objective is to transport these colonists to safety using a remotely piloted drone guided by a vehicle known as a surface skimmer.

This skimmer is under the control of the player and plays a crucial role in navigating the complex and dangerous environment of the space station.

These RUs are vital as they allow the player to purchase upgrades for both the skimmer and the drone, enhancing their ability to navigate and survive the increasingly difficult levels.

The drone, operating under the skimmer's control, is responsible for picking up colonists from designated landing sites and transporting them to escape shuttles.

The player must strategically guide the drone to ensure it avoids these threats while successfully completing its mission to rescue the colonists.
