The Bastion Protocol

Once believed eternal, the universe flourished with invention, democracy, and prosperity.

At the heart of this balance stood the Precursors—the universe’s sacred architects. They guided the rise of countless civilizations, bringing life and light to a universe that might otherwise have remained in darkness.

Then something emerged from the depths of the void.

Across the universe, worlds began to fall silent. Civilizations vanished, leaving little behind to explain their fate. Even the Precursors could neither understand what was happening nor halt its advance. The balance they had sustained for eons began to unravel.

In the final transmissions of worlds now lost, one name kept appearing.

The Entrophage.

The Precursors devoted their final efforts to a secretive superintelligence—one intended to awaken with the power to eradicate the Entrophage.

Before it could emerge, everything else was lost.

Only their final creation remained, waiting.

THE BASTION PROTOCOL

You've been appointed the new commander of The Bastion Protocol, a defense system established by the sacred Precursors to protect the universe from the seemingly endless Entrophage breaches.

At the center of each run stands your tower, which attacks automatically while you choose its upgrades and shape your build.

Defeat enemies to earn Entropy, which you spend on upgrades during the current run. Invest in damage, attack speed, defenses, or economy to keep your tower standing as the waves grow stronger.

You'll also collect Salvaged Parts, which fund permanent upgrades between runs. When your tower falls, these upgrades carry forward, helping you push further on your next attempt.

As you progress, enemies become tougher and introduce new abilities that challenge your strategy. A build that handles one threat may struggle against another.

Your tower also gains access to new weapons and upgrade systems, opening up more combinations to explore. Discover synergies, adapt your approach, and build a tower capable of surviving deeper into the Entrophage onslaught.
