Flight Log #17 — Solid Ground

Published on 9/4/2026

Zero-G Alpha 5.4.5 is live.

Since January you have been flying over planets. Now you can look at what you are flying over. Alpha 5.4.5 replaces the old quadrant minimap with a real terrain map, upgrades the surveying minigame for finding deposits into a tactical challenge, and puts a new consumable into the economy. It is the biggest single change to the surface layer we have shipped, and it is the first step of a much longer road — more on that at the end.

The map

Scan a quadrant fully and the minimap is gone. In its place is a large terrain map you can zoom into, down to a few metres.
Old minimap versus the new terrain map
Same quadrant, same NASA elevation data underneath. A quadrant is 32 × 16 km — 512 km² — and until this release you saw all of it as a single blurred thumbnail. The new Scan Local Map button resolves more detail wherever you are looking, at any zoom, without loading the whole quadrant. That is what makes the fine zoom levels affordable in a browser tab. Zoom in far enough and this is what the ground looks like:
Highlands terrain at five metres per grid
That scale bar says 5 metres. Being straight with you: the tiling and the number of terrain types are deliberately limited right now, and if you fly around a lot you will see the same textures repeat. The engine underneath is the part we spent the time on. New terrain types and better tiling are cheap to add from here; the generator was not.

Your ship, actual size

Land, zoom to maximum, hit Scan Local Map.

Surveying — the Explore button

Deposit-finding has moved onto the terrain map, and it is now something you play rather than something you wait for.

How it works: The clock in the screenshot above says 29 seconds remaining and a deposit signal 2.7 km away. That is the whole game in one line. Find them and they stay found:

The probe economy

The two probes are worth a paragraph on their own, because they are a new production niche.
Advanced Terrain probe, General Store
Basic Terrain Probe: 30 s 0.2 km/s 2.0 km Advanced Terrain Probe: 45 s 0.5 km/s 4.0 km Both sell at HQs in limited quantities, and both blueprints are available. Production cost is very low. If you have Synthesis skills, you can build them in bulk for a fraction of the shop price and sell them at HQs or on the Auction House. If you have been looking for something to make that people will actually buy every week, this is it.

Everything else in 5.4.5

Improvements

Fixed

Where this goes

This is the part we usually keep out of the public posts, so it stays here. The terrain engine is not the feature. It is the floor that other features have to stand on. With it in place, the road ahead is: Manual navigation and landing on the surface, instead of arriving by menu. Vehicles that drive on the terrain you can now see. First-person exploration on foot. Points of interest worth travelling to — alien structures, wrecks, artifacts. Eventually, player installations and colonies on ground you surveyed yourself. None of that is in 5.4.5. Nothing in the list above is playable today. We are telling you the direction because you are the people who have been here long enough to care about the direction — and because the order matters: none of it was possible last month, and all of it is possible now.

Zero-G in the press

Zero-G has a media patronage with Portal MMO, one of Poland's MMO sites. They have published three pieces on the game:
Portal MMO — Best MMORPG online games

Zero-G is growing stronger — the browser hard sci-fi MMO is getting a new planet system and survey probes — a news piece on exactly the release you are reading about.
Zero-G in the Portal MMO game encyclopedia — the full database entry.
Zero-G HD gallery — 16 screenshots.
All three are in Polish. Your browser will translate them, and it is worth a look — it is the first time anyone has written about the game in a language none of us speak.

The Bulwark Call — closed

The first expedition gated on faction reputation ended on 29 August after eight days. Twelve pilots enrolled. Three held the line all the way to a ranked finish: Congratulations to all three, and thank you to everyone who flew the Ares Rampart line. Twelve is a small number, and we knew it would be — the reputation gate was there to make the expedition mean something, and it did exactly what a gate does. The next one will be built on what we learned here.
