Interstellar Progression Overhaul
Interstellar Progression Overhaul is a curated Space Age modpack bridge that connects many planet, science, enemy, and endgame mods into one coherent progression route across multiple star systems.
IPO turns a large planet pack into an authored campaign spine instead of a pile of unrelated destinations. The current campaign is organized into five chapter systems:
- Solara — the launch frontier and familiar Space Age bridge
- Myridian — the cold long-range frontier
- Viridion — the specialist exotic branch and outer-board entry
- Pyraxis — the hazard corridor
- Terminus — the deep-space finale
1.2.0 — Science Compression & Stable Starmap
The 1.2.0 release combines Science Compression Polish with the accepted stable starmap candidate.
The protected route authority is:
```txt
Lignumis -> Nauvis
Fulgora -> Cerys only
Fulgora -> Viridion Slipstream
Myridian Slipstream -> Aquilo -> Tellus
Foliax -> Crucible Orbit/Approach -> Planet Crucible
```
## Features
- Five authored system chapters with slipstream anchors
- System science packs for chapter mastery
- Science compression pass for large late-research science-pack walls
- Discovery technologies for each campaign chapter
- Cleaner starmap route authority for large planet packs
- Lignumis start path support
- Fulgora-only Cerys route
- Myridian Aquilo placement
- Crucible Approach / Crucible Orbit gating for Planet Crucible
## Release focus
This release is focused on progression structure, starmap readability, and late-game science cleanup. The starmap has been frozen from the accepted in-game route review baseline; future 1.2.x work should avoid broad board rewrites unless a specific screenshot identifies a remaining issue.
