Interstellar Progression Overhaul — A Five-Chapter Space Age Campaign

Turn your collection of Space Age planet mods into one connected interstellar campaign.

Interstellar Progression Overhaul (IPO) transforms a large collection of supported Factorio Space Age planet mods into a structured, five-chapter progression experience.

Instead of dozens of independent planets scattered across the starmap, IPO brings exploration, research, science production and interstellar travel together into an authored campaign with clear objectives and meaningful progression.

What IPO Does

IPO is a curated, non-K2SO Space Age planet-pack campaign organiser.

Its main features include:

• Five interconnected star systems with distinct progression chapters.
• Story-driven slipstream routes connecting the major systems.
• Curated planetary placement for a cleaner, more readable starmap.
• Chapter-specific science packs incorporating supported planetary outputs.
• Research-controlled exploration that gates access to later chapters.
• Technology progression protection against discovery loops and deadlocks.
• Chapter reward technologies providing additional progression milestones.
• In-game Campaign Board showing objectives and unlock requirements.
• Planet-pack integration for supported worlds and optional dependencies.
• Compatibility handling for overlapping routes and discovery technologies introduced by supported mods.

IPO is designed to make a large planet modpack feel like one connected journey rather than a collection of unrelated destinations.

The Five-Chapter Campaign

The main interstellar progression follows:

Calidus → Solara → Myridian → Viridion → Pyraxis → Terminus

Chapter 1 — Solara: Launch Frontier

The opening chapter introduces the wider interstellar campaign.

Explore the early frontier, establish space infrastructure and prepare for travel beyond the starting planetary system.

Featured destinations include Igrys, Arig, Moshine, Panglia and other supported early-game worlds.

Chapter science: Solara System Science
Chapter reward: Solara Route Stabilization

Chapter 2 — Myridian: Cold Frontier

Expand into demanding environments and establish the industries required for sustained interstellar exploration.

Featured destinations include Tellus, Hyarion, Crucible, Vesta, Corrundum, Cubium, Aquilo and supported frontier worlds.

Chapter science: Myridian System Science
Chapter reward: Myridian Frontier Logistics

Chapter 3 — Viridion: Specialist Industries

Develop advanced planetary industries, specialised processing chains and new technologies.

Explore Rubia, Paracelsin, Ribbonia, Maraxsis and the Apia–Carnova binary system.

Chapter science: Viridion System Science
Chapter reward: Viridion Specialist Processing

Chapter 4 — Pyraxis: Hazard Corridor

Enter hostile environments requiring advanced equipment, specialised science and stronger industrial capabilities.

Explore Frozeta, Secretas, Foliax, Castra, Tenebris, Tiber and other supported hazard destinations.

Chapter science: Pyraxis System Science
Chapter reward: Pyraxis Hazard Operations

Chapter 5 — Terminus: Edge-Space Finale

The final chapter leads into deep-space exploration and endgame challenges.

Reach the outer frontier, explore the Dea Dia system, Prosephina, Lemures and supported endgame destinations.

Chapter science: Terminus System Science
Chapter reward: Terminus Deep-Space Integration

Interstellar Travel & Starmap

IPO organises supported planetary systems into a connected interstellar network.

The starmap features:

• Dedicated slipstream gateways between major systems.
• Authored interstellar routes following the campaign progression.
• Planetary connections organised into local exploration branches.
• Gateway placement designed to keep interstellar travel visually readable.
• Reduced route clutter and unnecessary crossings.
• Protection against dependency-created shortcuts that bypass the intended chapters.
• Preservation of supported optional exploration branches.

The goal is a starmap that communicates where you can travel, what comes next and how the wider campaign fits together.

Integrated System Science

Each chapter features a dedicated system science pack that incorporates compatible outputs from supported planets.

System science helps connect planetary exploration with industrial development, encouraging players to establish production across multiple worlds.

Examples include:

• Solara: Early frontier and supported planetary science outputs.
• Myridian: Tellus, Pelagos, Aquilo and cold-frontier outputs.
• Viridion: Rubia, Crucible, Paracelsin, Ribbonia and Maraxsis outputs.
• Pyraxis: Castra battlefield science, Tenebris bioluminescent science and Tiberium science outputs.
• Terminus: Supported deep-space and late-game production outputs.

Ingredients are integrated where compatible prototypes are available.

System science packs serve as chapter milestones while contributing to the wider research progression.

Research & Discovery Progression

IPO connects planetary discovery to the five-chapter campaign.

Chapter surveys control access to their corresponding system science packs and slipstream gateways.

The progression system is designed to:

• Prevent later chapters from unlocking prematurely.
• Keep important planetary discoveries behind appropriate research.
• Maintain meaningful dependencies between exploration milestones.
• Reduce circular technology prerequisites.
• Integrate supported planet discovery technologies into the campaign.
• Preserve legitimate exploration branches without creating unintended shortcuts.

Chapter reward technologies provide additional milestones as players advance through the campaign.

In-Game Campaign Board

The IPO Campaign Board provides an overview of your interstellar journey.

Accessible through the IPO interface button, it displays:

• Current campaign chapter.
• Required anchor worlds.
• Optional support worlds.
• Chapter science progress.
• Chapter reward research.
• Next progression objectives.
• Interstellar unlock targets.
• Terminus Endgame Bridge information.

The board helps players navigate a large modpack without constantly searching through the technology tree.

Chapter Reward Technologies

Each system science pack contributes to a dedicated reward technology.

These rewards give system science a visible role beyond conventional science compression.

Planet-Pack Integration

IPO is built around a curated selection of supported Space Age planetary mods.

It integrates compatible planet placement, discovery technologies, science outputs and interplanetary routes into the wider campaign.

Optional integrations are enabled where the relevant supported mods and prototypes are present.

IPO does not attempt to turn every available planet mod into a supported destination. Its focus is a coherent campaign across a maintained set of compatible worlds.

Difference from Razi Protocol

IPO and Razi Protocol serve different purposes.

Razi Protocol is a heavier K2SO/Krastorio-style mega-pack integration project.

Interstellar Progression Overhaul is designed around a curated Space Age planet-pack campaign without K2SO as part of its core identity.

IPO prioritises authored exploration, planetary organisation, chapter science integration, controlled progression and readable interstellar travel.

Requirements & Compatibility

• Factorio: Compatible Factorio 2.x version as specified in the mod dependencies.
• Space Age: Required.
• Forgeworks Core: Required; minimum supported version is specified in the mod dependencies.
• Supported planet mods: See the Mod Portal dependency list.
• Optional integrations: Enabled when compatible supported mods are installed.

Compatibility with arbitrary planet packs or unrelated progression overhauls is not guaranteed.

Existing Saves

IPO is designed to support continued campaigns where compatible migrations and dependency configurations allow.

Changes to planetary discovery, research prerequisites or interstellar routes may affect existing progression.

Back up existing saves before updating, particularly when using a large planet modpack.
