Aeterna Siege

The End is Their Beginning. Stand Your Ground. Earth is a memory. Humanity`s last bastion, the city of Aeterna, stands on the galactic fringe. As a Legionary of the final army, you are the wall against the endless alien horde. Engage in epic, large-scale battles where strategy, firepower, and sheer will determine the fate of our species. How long can you last?

Detailed Description

Welcome to the end of the world. Aeterna Siege is a next-generation tactical shooter that throws you into the boots of a battle-hardened Legionary in humanity's darkest hour. The majestic city of Aeterna, a marvel of technology and the last refuge of our civilization, is under constant, relentless assault from a terrifying extraterrestrial force known only as the Swarm. Your mission is not to win the war, but to survive the siege. Each day brings a new, more vicious wave of attackers. From skittering, razor-limbed drones to towering, city-smashing behemoths, you must master a vast array of weaponry and tactical equipment. The battlefield is a living entity; fortifications can be built and destroyed, the frontline shifts by the minute, and the environment itself can become a weapon. But you are not just a soldier. You are a symbol of hope. Your performance on the battlefield directly impacts the morale of Aeterna's citizens and the functionality of its defenses. Earn upgrades, deploy automated turrets, call in orbital strikes, and unlock the secrets of powerful ancient technology buried beneath the city. How many days can you hold the line? The siege is eternal. Your courage is not.

4 Stages of Gameplay

The Outer Wall:

The Outer Wall:

Your first stand. Learn the mechanics, face smaller waves of basic alien scouts, and fortify the city`s massive perimeter defenses. Every bolt and bullet counts.
The Siege Breakers:

The Siege Breakers:

The enemy adapts. Larger, more formidable beasts and armored creatures arrive, forcing you to master mobile combat, target weak points, and manage the integrity of the defensive grid under intense pressure.
Heart of Aeterna:

Heart of Aeterna:

The outer defenses have fallen. Battle now rages in the city`s industrial districts and plazas. Urban warfare takes over as you fight street-by-street, using the ruined architecture for cover and setting deadly ambushes for the invading swarm.
The Spire:

The Spire:

The final mission. The command Spire is all that remains. With resources depleted and the enemy at their most ferocious, you must make a last, desperate push to activate a doomsday protocol that could end the siege once and for all—or die trying.

True Scale of War:

Witness battles of unprecedented scale. Hundreds of enemies swarm the screen simultaneously, supported by colossal bio-mechanical Titans that serve as devastating level bosses, creating moments of pure, awe-inspiring chaos.

The Legacy of Aeterna:

Your actions have permanent consequences. Successful defenses unlock new narrative paths, permanent upgrades to the city, and reveal the deep lore of the siege through the stories of the citizens you protect.
