Campaign
Four campaigns, 40 operationsThe Broken Orbit (1–10), The Silent Citadel (11–20), The Venus Disturbance (21–30) and A Sky Without Orders (31–40), ten waves each. Operations 10, 20 and 30 end in an intermission carrying one epilogue and the next prologue; final victory follows operation 40.
Combat identity
Four-way faction hostilityEarth, Mars, the Belt and an alien fleet. The aliens fight everyone, the Belt and Mars fight each other, and a projectile or beam keeps its owner after the ship that fired it dies.
Station
Refit levels 0–5Maximum hull grows 3,600 → 7,200 and Nexus beam turret capacity 0 → 10; separate Nexus gun turret mounts grow 8 → 18, filled up to Gun turret mounts research (3 → 18). The Nexus is one of 14 operational stations, each with its own hull, shield and turrets.
Capacity
Logistics to 20 fleets, 24 with FoldFleet cap 3 → 6 → 9 → 12 → 15 → 20, plus four from Fold Logistics; mobile cap 27 → 216 units. Build admission counts queued ships, so the queue cannot oversubscribe a fleet.
Engine budget
3,072-unit entity poolBefore an operation starts, a catalog check reserves the full player fleet, every station and every authored ship across its ten waves. The heaviest case, operation 40, needs 2,963.
Persistence
Versioned checkpointsBrowser saves, downloads and imports share one serialised format. Saves from version 5 onward migrate forward. Loads validate before changing any state, and a corrupt file is rejected.
Art
20 theater illustrations, 71 portraitsHand-authored SVG briefing art in one etched-space style for operations 1–20, reused in campaigns III and IV, plus 71 portraits for the transmission system.
Pipelines
Scripted asset production371 GLB models including LOD variants, 346 KTX2 textures and 506 audio files, with committed import and generation scripts for models, LODs, textures and sound.
Tooling
Eleven review pages and a builderships, turrets, effects, explosions, missiles, stations, asteroids, nexus, avatars, sounds, planets at the developer origin root render the real libraries outside the game, so art and audio can be checked without playing an operation.
