A short-session space expedition in real time. Fly a randomised sector while the clock spends days you cannot get back. Any module fits any slot, one of each type. Rescue pilots mid-fight, run electronic warfare and remote repair, cloak and ram. One build for phone, tablet and PC.

Recorded from the build. Music from the game.
Any module fits any slot; one of each type. Fit a second shield and the first drops into the hold. Guns are the exception: a hull carries as many as it has mount points.
Webs, capacitor drains, sensor dampeners, the Veil Projector, remote shield and armour repair, power conduits. All of it works for you and against you.
Six specialists are out there, losing. Keep one alive through the fight and they fly with you. Berths cap at four, so you never collect them all.
Fights run in real time with quarter- and half-speed buttons, so you slow a fight to read it rather than stopping it.
Arriving on hostiles opens a radar sweep that reads their loadouts and lets you refit before you commit. Or withdraw, and pay for the trip twice.
Touch and mouse share one input path. The same static build runs on a phone, a tablet and a desktop, and it weighs 145 kB gzipped.
All art, music, sound effects and voice lines in Sector Prime were generated with an asset pipeline the developer built; the code was written with Claude Code under the developer's direction; the design, tuning and tests are the developer's own. Nothing is generated while the game runs. No third-party characters, art, logos or other copyrighted works were used as prompts or references. The same sentence appears in the Steam and itch disclosures.
Why say it this way: because the tag exists so you can decide, and because this game is also the working proof of that pipeline. If you filter generated-asset games out, this one belongs in the filter. If you want to know how it was done, the press kit lists what made what.
Linh Ngo, Binary Helix. Shipped Dangerous, a 3D space RPG, on four platforms between 2011 and 2014; Steam rated it Mostly Negative, and the lesson was to make a game that is short, readable and honest about what it is. Sector Prime is 43,000 lines of TypeScript with 470 tests holding it together, made by one person and a very fast assistant.
