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 REALITYChoose 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.<video class="bb_img" autoplay muted loop playsinline poster="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3501180/extras/3c4cfa4d1b308b5400c5847a0e2a9cf3.poster.avif?t=1771420855" width=616 height=338 ><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3501180/extras/3c4cfa4d1b308b5400c5847a0e2a9cf3.webm?t=1771420855" type="video/webm; codecs=vp9"><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3501180/extras/3c4cfa4d1b308b5400c5847a0e2a9cf3.mp4?t=1771420855" type="video/mp4"></video>OBSERVE THE SUBATOMIC PARTICLESDive into a vibrant cast of quantum entities, each inspired by real subatomic particles. From swift neutrinos to volatile quarks and enigmatic gluons, every character brings unique abilities and behaviors shaped by the laws of physics. Discover their strengths...and their instability! LET'S GET PHYSICAL!Every environment, mechanic, and enemy is based on real scientific principles! Wave-particle duality, entanglement, vacuum fluctuations and many more...each level is a playable representation of the weirdness of quantum mechanics! 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.<video class="bb_img" autoplay muted loop playsinline poster="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3501180/extras/c672bd53b03b47bfe9439a081704e874.poster.avif?t=1771420855" width=616 height=338 ><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3501180/extras/c672bd53b03b47bfe9439a081704e874.webm?t=1771420855" type="video/webm; codecs=vp9"><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3501180/extras/c672bd53b03b47bfe9439a081704e874.mp4?t=1771420855" type="video/mp4"></video>CHOICE SUPERPOSITIONThe 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.
