The game narrative begins with a peaceful period on Mars, where humans and the Swarm, a primitive alien species, coexist. However, this harmony is abruptly shattered due to certain known factors that cause the Swarm to mutate and become hostile. As these once friendly creatures turn aggressive, humanity faces a significant threat, and the players are placed in the role of defenders struggling to understand and combat this sudden transformation.
Protecting the human population and ensuring survival on Mars becomes the main objective for players. They need to uncover the reasons behind the Swarm's sudden aggression to address the root causes of the crisis. The game tasks players with establishing a strong base on Mars that can withstand attacks, develop strategic tactics, and collaborate with allies to preserve human civilization on this challenging planet.
Players are encouraged to explore uncharted territories on Mars, fight against the Swarm, and rescue stranded survivors. Progressing through exploration allows for expanding the base and increasing power, but players must be cautious of dangerous creatures like giant sandworms and spiders that inhabit the environment. Building alliances with others worldwide facilitates joint attacks and collective growth, emphasizing teamwork and strategic cooperation.
To strengthen their defenses, players can develop their Captain and recruit Heroes in space capsules, creating an elite squad capable of performing various missions. Careful planning in construction, technological research, and manufacturing advanced units like Mecha Warriors is essential for achieving victory. The game emphasizes strategic decision-making, collaboration, and resource management as players strive to be the great protectors of human civilization on Mars.
