The Terminids are the galaxy’s relentless swarm, a hive-mind species of evolving terror. They adapt to every attack, birthing larger, deadlier mutants like Chargers and Bile Titans to overwhelm defenses. Their spore-clouds, known as the Gloom, choke entire planets, cutting off communication and rendering worlds uninhabitable.

But they’re more than a threat—they’re a resource. The critical E-710 fuel flows from their monstrous biology, forcing Super Earth to harvest their worlds at great cost. Each encounter with the Terminids is a battle for survival, a clash against a foe that learns, adapts, and devours everything in its path.

The Automatons are cold, calculating killers—an endless army of machines driven by unyielding logic and a hatred for all organic life. Their forces range from relentless infantry drones to towering war mechs, each built for maximum efficiency in destruction. They adapt their tactics with chilling precision, exploiting weaknesses and overwhelming defenses with mechanical ruthlessness.

Their ultimate goal? To dismantle Super Earth and impose their sterile, lifeless order across the galaxy. Their factories churn endlessly, recycling captured materials—and even Federation citizens—into new units. Every encounter with the Automatons is a battle of attrition, their forces as unfeeling as the steel they’re forged from.

The Illuminate are the galaxy's enigma—a once-great aquatic species turned masters of psionics and advanced energy technology. They strike with precision, wielding devastating energy weapons, shields, and mind-bending psionic abilities that disorient and control their foes. Their shimmering forces seem otherworldly, almost ethereal, yet their intent is as sharp as any blade.

Beneath their brilliance lies a ruthless determination to reclaim their lost dominance in the stars. Their attacks are calculated, their defenses nigh-impenetrable, and their mysterious goals often at odds with humanity’s expansion.

These oversized insectoid creatures were encountered as humanity expanded into the galaxy. Early in the war, they were known simply as "The Bugs," and their method of spacefaring via meteor-like spores was only beginning to be understood. 

Originating from Cyberstan, these human-machine hybrids sought independence from Super Earth's authoritarian regime. The rebellion was ideologically driven, with the Cyborgs establishing a socialist society contrary to the Federation's managed democracy. 

Once a powerful aquatic empire, the Illuminate presented themselves as a highly advanced civilization. Despite their initial overtures for peace, the Federation perceived their vast energy-based weapons and shielding technologies as threats.
