Razi Protocol

Razi Protocol is a large progression, compatibility, and space-map overhaul for Factorio: Space Age. It is built for a huge Krastorio 2 Spaced Out planet pack, and its job is to make that pack feel like one connected expedition instead of a stack of unrelated planet mods.

The mod adds a new system-based progression structure, reorganizes where many planets live, rebuilds discovery technologies, adds system tech cards, routes custom enemy factions to planets that fit them, replaces Nexus omega science clutter with a single Deep Space card, and creates a longer endgame around the Krastorio intergalactic transceiver.

What Razi Protocol Adds

A staged galaxy route across custom systems: Calidus, Solaris, Nyxaris, Vibrant, Beetlejuice, and Deep Space.
New system discovery technologies for Solaris, Nyxaris, Vibrant, and Beetlejuice.
New system tech cards for Calidus, Solaris, Nyxaris, Vibrant, Beetlejuice, and Deep Space.
A reworked science progression where later systems use cards from earlier systems instead of requiring giant walls of individual science packs.
A custom deep-space route after Aquilo, including Nexus, the black hole approach, black hole, Oort Cloud, and Sol.
A Krastorio 2 Spaced Out transceiver endgame chain with Intergalactic Singularity Theory, Intergalactic Singularity Test Fire, Stable Intergalactic Singularity, and Intergalactic Signal Lock.
A Deep Space Tech Card that replaces the many Nexus omega science packs in research requirements and hides the omega-pack clutter from normal play.
Planet-specific enemy placement for arachnids, armoured biters, cold biters, electric flying enemies, explosive biters, and toxic biters.
Vanilla biter and worm autoplace suppression on planets where a custom enemy faction is meant to be the main threat.
Science Tab compatibility that moves system cards, planet science packs, and research data into cleaner science subgroups.
Compatibility patches for K2SO enhancement/tweak mods, route assumptions, lab inputs, and several prototype load edge cases.
A forced Tellus setting override so Tellus does not move Maraxsis away from Razi Protocol's intended system layout.

Progression Flow

Razi Protocol treats the run like a series of chapters.

Calidus is the inner-system and base Space Age foundation. It includes the normal base and Space Age sciences, plus early inner-system worlds such as Muluna and Cerys. The Calidus Tech Card compresses that early foundation into a card used by later progression.

Solaris is the first major custom system layer. It brings in Castra, Arig, Hyarion, Tellus, and Corrundum as a connected branch. Its card combines the Solaris-tier science packs, including battlefield, Planetaris, and electrochemical style science.

Nyxaris is a shared mid-tier system for both Nyxaris and Dea Dia progression. It integrates Dea Dia into the Nyxaris region and places Apia Carnova, Moshine, Panglia, and Pelagos into the same broader stage. Its card combines aerospace, Dea Dia, insulation, thermodynamic, nuclear, apicultural, and Pelagos style science.

Vibrant is the strange exotic system. It contains Ribbonia, Paracelsin, Secretas, Frozeta, Rubia, and Maraxsis. Its card combines the alien, recycling, biofusion, galvanization, golden, and hydraulic style sciences from that chapter.

Beetlejuice is the harsh late-game planetary system. It includes Cubium, Tenebris, Crucible, Vesta, and Aquilo, then leads onward to the solar system edge. Its card combines bioluminescent, cryogenic, gas manipulation, and Crucible science before the player moves into deep-space progression.

Deep Space is the endgame chapter. It places Nexus after the solar system edge, then uses the black hole approach, black hole, Oort Cloud, and Sol as the final route. This is where Nexus, Void Processing, Sol, promethium, antimatter, and the transceiver gate all start tying together. The Deep Space Tech Card becomes the compact replacement for Nexus omega science and is used for the last stretch of research.

System Cards

The system card system is the main cleanup pass for the technology tree. Instead of making every late research require dozens of individual planet packs, Razi Protocol converts earlier system mastery into a smaller set of milestone cards.

Calidus Tech Card: made from base, Space Age, and early inner-system science packs.
Solaris Tech Card: made from Solaris-tier planet sciences.
Nyxaris Tech Card: made from Nyxaris and Dea Dia tier sciences.
Vibrant Tech Card: made from Vibrant tier sciences.
Beetlejuice Tech Card: made from Beetlejuice tier sciences.
Deep Space Tech Card: made from Beetlejuice and deep-space endgame sciences.

These cards are added to labs automatically when the relevant tools exist, and Science Tab support moves them into a cleaner science-card row.

Endgame Changes

Razi Protocol intentionally conflicts with several extended-endgame mods because it provides its own ending path.

Nexus normally adds many omega versions of existing science packs. Razi Protocol hides those omega packs and swaps their research requirements to the Deep Space Tech Card instead. That keeps Nexus in the endgame without turning the technology screen into a rainbow brick wall.

Void Processing is pushed beyond the Nexus and transceiver gate. Black-hole discovery uses the endgame science stack, then leads into the void-science side of the final deep-space route.

The Krastorio intergalactic transceiver is also moved later. Instead of simply unlocking it at the normal K2SO point, Razi Protocol adds a three-step singularity chain. Once the stable singularity research is completed, the transceiver recipe unlocks. After the transceiver is activated in-world, a trigger technology called Intergalactic Signal Lock completes and opens the path into Nexus and Sol related deep-space research.

Enemy Routing

Razi Protocol moves several enemy mods away from Nauvis-style generic spawning and toward planets that fit their theme.

Arachnids spawn on Arig, Nexus, and Crucible.
Armoured biters spawn on Panglia, Hyarion, Nexus, and Crucible.
Cold biters spawn on Aquilo, Paracelsin, Frozeta, Cerys, and Nexus.
Electric flying enemies spawn on Corrundum, Ribbonia, and Nexus, in addition to their original Fulgora behavior from the source mod.
Explosive biters spawn on Moshine and Nexus.
Toxic biters spawn on Cubium, Vesta, Nexus, and Crucible.

On planets where Razi Protocol assigns custom enemies, it also suppresses vanilla biter and worm spawns so the custom faction is not buried under default enemy noise.

Space Map Layout

The mod adds or moves many locations and routes with PlanetsLib. The current route is roughly:

Calidus slipstream connects the early star region to the custom systems.
Solaris contains Castra, Arig, Hyarion, Tellus, and Corrundum.
Nyxaris contains the Nyxaris slipstream, Dea Dia system access, Apia Carnova, Moshine, Panglia, and Pelagos.
Vibrant contains Ribbonia, Paracelsin, Secretas, Frozeta, Rubia, and Maraxsis.
Beetlejuice contains Cubium, Tenebris, Crucible, Vesta, Aquilo, and the edge of deep space.
Deep Space contains Nexus, the black hole approach, black hole, Oort Cloud, and Sol.

Some original planet-mod routes are deleted or replaced so the intended progression path stays clean.

The solar system edge also acts as the bridge out of Beetlejuice. Its research is designed to require system-card progress through Beetlejuice, while the deeper Nexus and Void Processing sciences come after that point.

Compatibility Work

Razi Protocol includes compatibility logic for:

Krastorio2 Spaced Out endgame and transceiver flow.
Nexus omega science replacement.
Science Tab grouping and lab input fixes.
xy-k2so-enhancements route assumptions around Moshine.
nulls-k2so-tweaks and related K2SO tuning dependencies.
Maraxsis and K2SO electric mining drill collision masks, keeping drill upgrades valid after Maraxsis adds underwater build rules.
Tellus' adjust-maraxsis setting, which is forced off so Maraxsis stays in the Razi Protocol layout.
Bioluminescent prototype load issues from missing place results or next-upgrade targets.
Multiple enemy mods that otherwise try to spawn on Nauvis or generic planet tiles.

Major Required Content Mods

Razi Protocol is designed around a large dependency set. Major content mods include Krastorio2 Spaced Out, PlanetsLib, Terra Palus, Muluna, the Planetaris planet set, Cerys, Dea Dia, Corrundum, Apia, Moshine, Panglia, Pelagos, Tenebris Prime, Secretas, Maraxsis, Rubia, Nexus, Void Processing, Vesta, Castra, Crucible, Ribbonia, Dyson Sphere Reworked, and several enemy mods.

It also supports a number of optional quality-of-life and compatibility mods. For the intended experience, use the optional mods listed in info.json where possible, but avoid adding extra collision-layer-heavy mods unless you know the total pack still fits under Factorio's hard collision-layer limit. combat-mechanics-overhaul is not listed as an optional dependency for that reason; it can push this pack over the 55 collision-layer engine cap when combined with several water, vehicle, enemy, and planet mods. Lignumis is also marked as incompatible for now because the full Razi Protocol pack already sits too close to that same collision-layer cap.
