Echo Zero

---

You Are Zero

You awaken as an expendable clone in a labyrinth of steel that’s collapsing into living hives. Tasked by the ominous corporation DOME, you must scavenge, build, and eradicate Organism K-23.77XY (also mainly referred to as Organism K2); a rapidly mutating species threatening to breach the surface. Each death transfers your mind to a new, randomly generated clone. Every failure brings the hive creatures closer to escaping your shared underground prison.

Above it all, JUNO watches; your warm, motherly AI overseer and DOME’s sole intermediator. As you progress, she provides upgrades, privileges, and subtle rewards that expand your power while tightening her hold over your mission.

Explore

The world of Echo Zero is beautiful, dangerous, and ever-changing. Each run spawns a new version of the underground. Randomised rewards, upgrades, resources and wildlife growth patterns all affect your combat and construction strategies. But beware the **Violet Bloom, **where Organism K2 fully blossoms, sending its twisted spawn into overdrive.

Expand

Defend your base at all costs! At its heart, the generator powers your survival. Build barricades, upgrade turrets, and deploy droids to repel relentless waves of enemies. With randomized upgrades and strategic positioning, every run is a fresh tower defense challenge.

Engage

The various offspring of Organism K2 behave in different ways, forcing you to rely on precise movement, synergistic build paths, timed reloads, and an ever-expanding team of robot companions. Wargear and mutations grant powerful passive effects and abilities, while scarce ammo makes every shot count. Randomised equipment, countless synergy paths, and badass upgrades ensure each run feels different.
