Welcome to Razi Protocol 3.0

Razi Protocol brings an enormous collection of Space Age planets, industries, enemies, and technologies into one connected expedition. Explore seven star systems, build factories across dozens of worlds, and establish the research and logistics networks needed to reach the farthest parts of the galaxy.

The journey begins on Nauvis, but your first factory is only the beginning. Each star system has its own industries and a central System Tech Card that brings its planets' research together. New discoveries open the way forward, while existing production lines continue to play a part in your campaign.

Along the way, the Expedition Journal records your quests, milestones, and major construction projects. A curated starmap gives you meaningful travel choices, and increasingly ambitious engineering goals take you from your first space platform to the Dyson Sphere, the Transceiver, Deep Space, and finally Convergence.

Razi Protocol doesn't replace the original mods or their unique mechanics. It connects them, giving their worlds, resources, and technologies a shared purpose.

Please Read Before Starting

• A new save is strongly recommended for 3.0. Upgrading an existing 2.0 save may be possible, but it can require manual fixes. Make a backup first.
• Check the Dependencies tab. Space Age, Krastorio 2 Spaced Out, and the required planet and companion mods form the intended experience.
• Progression changes from the beginning. This is a connected campaign, not just a collection of planets added after the normal Space Age ending.
• Normal is the recommended difficulty. Easy, Hard, and Nightmare offer alternative challenges, with more detailed controls available in the settings.
• Some settings require restarting Factorio. World-generation changes do not affect already-generated terrain, and major progression changes can affect existing saves.
• Use the Expedition Journal. Press Ctrl + Shift + J to review objectives, projects, and recorded milestones.
• 3.0 is still in development. Features, balance, compatibility, and progression may change before release.

Razi Protocol Is for You If

• You want a long Space Age playthrough built around interconnected worlds rather than isolated planet visits.
• You enjoy complex science trees, specialized factories, and interplanetary production chains.
• You like planning cargo networks, crossing dangerous routes, and making distant outposts work together.
• You want major engineering projects and a physical endgame to build toward.
• You want the freedom to adjust difficulty, resources, enemies, travel, and visuals to your own playstyle.

Explore the Galaxy

Razi Protocol organizes its worlds into seven major star systems, each with its own identity, industries, and place in the wider expedition. The starmap connects them through curated routes, with danger colors and travel information to help you decide where to go next.

Your starting system, Calidus, establishes the foundations. Beyond it, the galaxy opens into paired frontiers where you can choose which branch to explore first. Reaching the outer regions still requires the research and infrastructure built along the way.

• Calidus: Your starting system, home to Nauvis, Muluna, and the foundations of the Dyson Sphere.
• Solaris & Nyxaris: The first frontier, opening major industrial and biological research branches.
• Vibrant & Vespera: A second frontier of specialized industries, demanding environments, and increasingly important freight routes.
• Beetlejuice & Umbra: The outer systems, where resources, hazards, and infrastructure requirements test the network you've built.
• Beyond: Bellicos, Aegis, Deep Space, and the road to Convergence.

Every system contributes something to the larger campaign. Its research feeds a regional Tech Card, and its production helps support the journeys that follow. The galaxy is meant to feel vast without turning navigation into guesswork.

Make the Galaxy Yours

Not every engineer wants the same kind of challenge. Razi Protocol includes a broad range of settings so you can shape the campaign around exploration, logistics, combat, industry, or a mixture of them all.

Start with Easy, Normal, Hard, or Nightmare. Normal provides the intended balance. If you prefer more control, you can adjust individual systems without rebuilding the entire experience from scratch.

• Difficulty & Threats: Enemy density, evolution, expansion, raids, pollution, defenses, and Nexus threats.
• Resources & Industry: Resource frequency, patch size, richness, spoilage, research costs, rocket costs, and factory throughput.
• Worlds & Encounters: Habitats for supported Armoured, Cold, Explosive, Toxic, Arachnid, and Electric enemies.
• Asteroids & Belts: Asteroid populations, space hazards, ore richness, salvage, and quality asteroids.
• Industrial Integration: Cross-world trade, planetary dependencies, technology distribution, and supported transport routes.
• Stellar Projects: Dyson Sphere and HELIOS research, construction options, and stellar hazards.
• Navigation & Quality of Life: Route colors, brightness, tooltips, starmap information, and recipe visibility.
• Galaxy Visuals: Star halos, nebulae, belt dust, orbit rings, and other background details.
• Performance: Optional reductions to particles, fragments, smoke, and other visual effects.

You can leave everything at its recommended defaults, or tune the parts of the expedition that matter to you. Performance reductions are optional and are not required for the intended visual experience.

Note: Some changes need a restart, and adjustments to progression or world generation can affect save compatibility. Back up your save before making major changes.

The Expedition Journal

When your factories stretch across multiple star systems, it's easy to forget what you were working toward. The built-in Expedition Journal keeps your goals, achievements, and supported system readouts together without forcing you to follow a rigid checklist.

The Journal has three main tabs: Quests, Projects, and Systems.

Quests: Follow Your Expedition

The campaign is organized into chapters with milestones tied to research, exploration, construction, and logistics. Review completed objectives, find unfinished work, or look back at the progress you've made.

• Chapter Progress: Follow the expedition from early industry on Nauvis toward Deep Space.
• Practical Objectives: Advance by researching, building, transporting, and discovering things in the game.
• Milestone History: Review completed objectives and your remaining goals.
• Next Steps: Find a useful direction when you're unsure what to tackle next.

Projects: Build Something Bigger

Research alone won't complete Razi Protocol's biggest undertakings. The Projects tab follows their technology requirements and the practical work still left to do.

• First Space Platform: Establish your first operational platform beyond Nauvis.
• Operation Beltbreaker: Prepare for hazardous asteroid crossings.
• Dyson Sphere: Pursue stellar research and construct the supporting infrastructure.
• The Transceiver: Work toward opening the route into Deep Space.
• The Ninefold Signal: Face nine Nexus bosses through their actual encounters.
• Project Ark: Prepare an expedition beyond the established systems.
• The Convergence: Bring your research, industries, and logistics together for the campaign's final challenge.

A technology unlock may begin a project, but you'll still need to build, deliver, and operate the infrastructure behind it.

Systems: Keep an Eye on Your Network

The Systems tab collects available readouts from supported companion mods while leaving their original controls intact.

• Fleet Logistics: Available Planet Express information about your cargo network.
• Zero-Point Energy: Supported Nexus reactor infrastructure and construction limits.
• Nexus Environment: Environmental conditions, shielding, and stabilizers where the source mod exposes them.
• Live Readouts: Useful operational information in a single view.

The Journal is there when you need guidance, and it stays out of the way when you'd rather explore on your own.

Open the Expedition Journal with Ctrl + Shift + J.

Science & Technology

Razi Protocol brings the research from its many planet and content mods into a larger progression. Instead of treating each world's discoveries as separate unlocks, the technology tree connects them to the systems around them and to the expedition as a whole.

Seven Systems, Connected Research

Each major star system has a System Tech Card that ties together research from its planets. Reaching that milestone requires more than discovering a location: you'll need to develop the industries and science branches that make the system valuable.

• Planetary Research: Explore original technologies, resources, and production chains from the integrated mods.
• System Tech Cards: Connect a system's planetary discoveries through a shared research milestone.
• Cross-System Progression: Build on earlier discoveries to reach the next frontier.
• Industrial Specialization: Give different planets lasting roles in science and manufacturing.
• Advanced Research: Work toward the technology and infrastructure required for the outer galaxy and Deep Space.

Research with a Purpose

A new planet brings new possibilities, but it doesn't erase the work you've done elsewhere. Later technologies draw on the factories and supply lines established earlier in the campaign. Planning how to produce and transport science becomes part of exploration itself.

The aim isn't simply to make research more expensive. It's to give discoveries a logical place in a much larger progression, while keeping the original mods' technologies and mechanics recognizable.

From Science to Stellar Engineering

The most advanced research supports the Dyson Sphere, the Transceiver, and eventually Convergence. Unlocking the technology is only one part of the challenge. Constructing and operating the projects is another.

Your research opens the way. Your factories make the journey possible.
