Pax Autocratica Core Fragments and Named Cores

Core Fragments are the fine print of Pax Autocratica buildcraft. Where generic weapon cores rewrite handling categories, fragments and named cores often target a specific gun or create sharp synergies that only appear when you hover combination hints in the selection UI.

What changed in late Prologue patches

Steam community notes for the Prologue era documented several systems that officers should expect to meet—or see evolved—in Early Access:

• New cores such as Void Detonation, Orb Resonance, Shield Rupture, and Power Shift
• Combination hints when hovering cores you already own
• Weapon-specific Core Fragments for kits like the Nebula Pistol, Nebula Assault Rifle, Gratov Quantum Longbow, and Defensive Shotgun
• Tutorial default weapon shifts toward the Nebula Assault Rifle with Laser Rifle fragment support
• Capture Lock as an active skill that pairs with capture-friendly cores

Names and drop rates will keep moving. Use this page as a planning language, then verify live tooltips.

Pax Autocratica overview for core and combat context

How fragments differ from broad cores

Broad weapon cores bend categories: control, sustain, burst, close pressure. Read Weapon Cores.

Combination cores glue sets together. Read Combination Cores and Best Core Combos.

Fragments are often gun-identity modifiers. Picking a Nebula Assault fragment when you main a shotgun wastes the synergy. Decide your three weapon slots before the expedition, then prioritize matching fragments.

Loadout workflow

1. Lock a doctrine in the Core Loadout Planner.
2. Choose weapons that already exist in your permanent unlocks.
3. Prefer fragments that reinforce that gun’s job (longbow poke, shotgun hold, AR mid-range).
4. Spend one slot on a control or capture-friendly tool if you need prisoners—see Capture, Convert, Sacrifice.
5. Leave greed slots empty rather than taking anti-synergy trash when the board is full.

Reading the new named cores

Treat patch-born names as roles, not fashion:

• Void Detonation style kits favor clustered kills after a control clump.
• Orb Resonance style kits reward stacking compatible orbs or repeating procs—check hover hints.
• Shield Rupture style kits help against armored or barrier elites before capture or execute.
• Power Shift style kits often trade one resource for another mid-fight; only take them if you understand the cost.

When unsure, default to control + sustain until the colony can afford experimentation.

Linking fragments to run progression

Fragments collected on a run usually behave like temporary roguelite power unless a patch explicitly promotes them into permanent unlocks. Do not rebuild the entire colony because one fragment felt strong. Permanent investment rules live in Run Progression.

Faction and map context

Aggressive factions such as Outlaws of Alysia punish pure damage fragment greed. On their maps, keep a control core even if a shiny Void-style pickup tempts you. Geography that funnels these fights sits under Sectors.

EA ranking humility

Public tier lists will lag patches. Keep two flexible kits: a control-capture kit and a burst-clear kit. Refresh Cores Tier List after Steam notes summarized in Updates.

Practice loop

Run short expeditions after each patch to learn new hover hints. Write down which fragment actually changed your gunfeel. That notebook beats rumor screenshots.

Core Fragments are how Pax Autocratica keeps the FPS half feeling personal while the colony half stays systemic. Collect with intent.
