Tutorial 1 - fly the space
Overview
Zero-G is a persistent, single-shard Space MMO made by a three-man team of veterans from the 90s MUD era in Rome, Italy. Version 5.2.0 adds full mobile support, the Expeditio: The Vespucci Quest, and Venture Depots.
There is no brake button. To dock, you must rotate your ship 180 and plan your deceleration with Flip & Burn by calculating mass, inertia, and Tsiolkovskys rocket equation. Newton is the only judge in the vacuum.
We imported NASA's LOLA and MOLA datasets. Every lunar crater and Martian canyon is mapped with metric precision, and terrain elevation directly impacts mission success.
Player Organizations, called Ventures, can claim terrestrial quadrants and build Depots. Hostile fleets now use Jump Drive tech, and the first Purple Heart Medal was awarded to a pilot who lost a heavy freighter near Mars.
