WHAT DO YOU NEED?

This unofficial guide is repinned directly to the uploaded GRUNTZ source archive 2026.08.28.0548. XML/source-backed values are read from extracted game files. Runtime behavior stays marked runtime-extracted, modelled or unknown until it is proven from the current build. Use Medical Sim for field treatment, serious injuries, surgery and resuscitation in one unified patient workflow.

SOURCE-BACKED

Raw GRUNTZ archive is authority

The data file is generated from gruntz_linux-x64_v2026.08.28.0548.tar.gz. CM-SS13 pages are only checklists for what to inspect.

Chemistry is source-exported

Reagent and reaction definitions come from shipped XML files, including medical properties, metabolism, overdose thresholds, catalysts and outputs.

Surgery definitions are source-exported

Operation gates, tools, zones, priorities, base ticks, pain requirements and authored outcomes are generated from SurgeryOps.xml.

Hidden runtime stays separated

Rules that live only in compiled code are labelled runtime-extracted when proven by the current binary audit, or modelled/unknown when they are still training assumptions or unsupported.

Provenance: this release is generated from the uploaded 2026.08.28.0548 standalone build archive. XML/source-backed values are marked as source-backed; behavior hidden in compiled runtime code is kept separate and is not presented as an extracted equation.

QUICK TRIAGE

Use the HF2 health analyzer whenever possible. These are the common first responses, not a substitute for reading the casualty.

CORE RULES

Bleeding first.Stop active external bleeding before waiting for recovery.
Symptoms fixed ≠ fully healed.A repaired fracture or organ does not automatically remove remaining brute, burn, oxygen or blood loss.
Internal problems escalate.Internal bleeding, embedded objects and organ damage belong in the trauma/surgery workflow.
Dead has a timer.The current build sets a 300-second revive window; completed CPR can extend it.
Medication can overdose.Use the Medical Sim and chemistry workspace to see verified doses, effects and authored overdose thresholds.

COMMON IN-GAME INTERACTIONS

These are practical inventory/UI details confirmed from the current build data or observed current-build tooltips. They are kept separate from the medical simulation rules.

[UI]Pill bottlesLClick takes the bottle. Alt + LClick draws one pill.
[UI]Medical stacksFor stacks such as splints/trauma kits, LClick takes the stack and Alt + LClick takes one.
[UI]Portable surgical bedCtrl + LClick drags the deployed bed. [DATA] The bed has an authored fold action back into the portable item and buckling forces the patient to lie down.
[DATA]Defib + sling strapThe stowed defib is Medium; the armed/ready defib is Large. The sling accepts up to Medium, so switch the defib safety back on before trying to stow it.

WHAT IS SOURCE-BACKED?

Source-backed means the value comes directly from the extracted GRUNTZ archive: item definitions, doses, overdose limits, reagent properties, reaction recipes, surgery operations/gates, CPR values, revive window, loadout contents and storage rules.

WHAT IS STILL LIMITED?

Runtime Extracted means the behavior is proven from the current binary audit. Modelled and Unknown remain training assumptions or unsupported until proven from GRUNTZ files.

EARLY ACCESS / VERSION-SENSITIVE: parsed game data is pinned to . Values that require the current runtime binary are not guessed. Game assets remain property of their respective rights holders.

SURGEON / DOCTOR STARTING LOADOUT

Parsed directly from Loadouts.xml. Gear is grouped by the slot/container where it starts, including the surgical webbing vest attached to the uniform.

SURGEON'S M276 LIFESAVER BAG

The contents below come from Loadout.Surgeon, not from the separate generic Lifesaver.Full entity. This matches the actual starting belt specified for the Surgeon class.

Why this matters: the generic M276 ... Lifesaver.Full definition has a different prefill (including epinephrine and Dexalin Plus). The Surgeon loadout equips the normal M276 and explicitly supplies its own contents.

STORAGE RULES

CM-SS13 reference policy
CM-SS13 Wiki is used only as a mechanism index/checklist. Medicine, Surgery, Chemistry and Ordnance pages tell us what inherited-style systems are worth searching for. No CM number, threshold, recipe, surgery rule or equipment requirement is treated as a GRUNTZ fact. Every published GRUNTZ conclusion is independently confirmed in this build's XML/Defs or compiled runtime.
Confirmed divergences include fracture thresholds and custom chemical-grenade construction/triggering.

ACCURACY & DATA FIDELITY

This release is repinned to the uploaded/current Linux archive shown in the live build badge. Authored data, compiled-runtime behavior and remaining simulator assumptions are visibly separated.

CONFIRMED / SOURCE-BACKED

    MODELLED / RUNTIME-DEPENDENT

      Real-time trainer model: generic continuous blood-loss rates and some secondary physiology display states are training approximations and can be disabled. Runtime drug metabolism cadence is separately audited from the current build.

      MECHANIC AUDIT STATUS

      WHAT CHANGED IN THIS SOURCE CHECK

      Reproducible source intake: the raw Drive archive is cached, extracted and validated before data export.
      Generated chemistry: all — implemented reactions are parsed from the three reaction files. Coagulex and Osteracil recipes come from the shipped definitions.
      Generated reagent catalog: reagent properties, metabolism and overdose thresholds are parsed from shipped reagent files. Active drug effects use the runtime-audited 40-tick metabolism cycle.
      Generated surgery operations: operation gates, tools, priorities, ticks, pain requirements and outcomes are parsed from SurgeryOps.xml.
      Runtime boundary is explicit: revive/defib classifier details, surgery formulas, medication effects and chemistry holder behavior are cited from the current 1257 runtime audit where proven.
      UI source status: item, drug, reaction and domain views now show source-backed/runtime/modelled/unknown status badges.
