The year is 2264. After a century of climate crises and global pandemics, humanity has finally turned its gaze toward the stars, not as a dream, but as a survival necessity. Zero-G is a persistent, single-shard Space MMO that simulates the inner Solar System using 1:1 NASA topographic data and uncompromising Newtonian physics. There are no "space-brakes" here, only momentum, mass, and the cold reality of the vacuum. The era of simple exploration is over. Under the guidance of the Vatican Academy, humanity has established a permanent presence across the Moon, Mars, and Venus. But as the first private Ventures begin to claim terrestrial quadrants and build trade depots, a new shadow has fallen over the system. An aggressive Alien Incursion has begun. Utilizing a terrifying "Jump Drive" technology that defies our understanding of Newtonian flight, these fleets have struck the first blow near Mars, leading to the first persistent player casualties in history. You are a pilot in this unfolding conflict. Starting from the Grottaglie Spaceport, you must master the "Flip & Burn" mechanics of realistic space flight to navigate the 1:1 scale of our Solar System.
