About This Game

COLLIDE WITH THE QUANTUM REALM

As a massive neutrino, you'll journey through the ever-shifting depths of the subatomic universe. Face the elusive Higgs Bosons and chase the shadows of a hidden force that defies all known physics, in a realm where reality bends, probabilities collapse, and every particle holds the key to rewriting the universe.

SHAPE YOUR RUN, BEND REALITY

Choose from a wide range of quantum tools, each with unique playstyles and surprising synergies. Weapons and upgrades let you shape every run, crafting builds that reflect your approach to conflict. Unleash attacks that bend space, manipulate mass, and unlock your full potential.

DECAY FAST, MOVE EVEN FASTER

Lose yourself in the relentless frenzy of the quantum realm, where hesitation is not an option. Momentum is survival: the faster you move, the longer you endure. Slow down and decay will inevitably catch up with you, speed up and you'll outrun your own collapse.

LET'S GET PHYSICAL!

Dive into a vibrant cast of quantum entities, each inspired by real subatomic particles, in a world entirely grounded in scientific principles. From swift neutrinos to volatile quarks and enigmatic bosons, every character, environment, mechanic, and enemy is shaped by the laws of physics. Wave-particle duality, entanglement, vacuum fluctuations, and more are not just concepts, but systems you will play, master, and survive within.

TOGETHER AS ONE
You are not a single being. You are a population. Entanglement gives you a shared consciousness projected across multiple units. Every failure is just another observation. Every return, another chance to collapse. Start over, but carry with you what you’ve come to understand.

NEW RUN NEW RULES

Each time you start over with a new neutrino, a fresh configuration awaits: rooms, paths, and weapons are reshuffled to offer a constantly changing challenge. No run is ever the same! Your combat style shifts, your discoveries vary, even your enemies evolve. Get ready to adapt, explore, and uncover new combinations every time.

CHOICE SUPERPOSITION

The quantum universe of Mass Eve is unstable, on the verge of collapse, and searching for balance. Two opposing forces struggle to shape its fate: one pushing toward entropy and radical change, the other seeking to preserve order and the coherence of fundamental laws.
Your actions, the alliances you forge, and the systems you choose to defend or dismantle will determine the weight of your trajectory. In a world where every observation has consequences, choice isn’t an option—it’s inevitable.
