Surgeon Simulator

Surgeon Simulator — Operating Room: Code Blue Edition

Developer: Happystoner5420 Games

Platform: HTML5 Web Browser Game (Fully Offline Playable)

Genre: Medical Simulation / Surgical Precision Game

Game Overview

Surgeon Simulator is a high-stakes, photoreal surgical simulation game where you perform life-saving operations against the clock. Every operation features a randomly generated patient with unique vitals, medical history, and complications. The game combines precise tool-based mechanics with real-time patient monitoring, creating an intense emergency room experience.

Core Features

5 Surgical Procedures

Appendectomy (🩹) — Remove an inflamed appendix

Cardiac Bypass (❤️) — Open the chest and graft a coronary artery

Trauma Laparotomy (🚑) — Stop internal bleeding after major trauma

Open Fracture Repair (🦴) — Realign and pin a broken bone

Emergency Resuscitation (⚡) — Stabilize a crashing patient, then operate

9 Medical Tools

Scalpel — Make precise incisions

Bone Saw — Cut through bone (sternum)

Forceps — Clamp bleeding vessels

Retractor — Hold incisions open

Scissors — Cut tissue and perform extractions

Laser Scalpel — Cauterize and seal vessels

Surgical Needle — Suture wounds closed

Drill — Place fixation screws in bone

Defibrillator — Emergency cardiac resuscitation

Gameplay Mechanics

Step-Based Surgery System

Each procedure is a sequence of 4-7 surgical steps. You must:

Use the correct tool for each objective

Work within highlighted zones on the patient's body

Perform actions precisely: drag for incisions/sawing, click for stitches/clamps

Manage complications like bleeding and cardiac arrest

Real-Time Patient Monitoring

Monitor 4 vital signs displayed in the HUD:

Heart Rate (with live ECG waveform)

Blood Pressure (Systolic/Diastolic)

SpO₂ (Blood Oxygen Saturation)

Blood Loss (progressive meter)

Vitals degrade based on your performance. Unclamped bleeders cause rapid blood loss. Let vitals collapse and the patient dies.

Bleeding & Blood Management

Incisions spawn bleeding points that pulse and spread blood

You must clamp each bleeder with forceps to stop blood loss

Blood loss affects heart rate, blood pressure, and oxygen levels

Blood decals and particle effects create visceral realism (toggleable)

Emergency Events — Cardiac Arrest

Patients can suffer sudden cardiac arrest mid-surgery (difficulty-dependent)

You have 7-14 seconds to grab the defibrillator and shock the patient

Success restores rhythm and vitals; failure ends the operation

Scoring System

Earn points for:

Completing steps accurately

Clamping bleeders quickly

Maintaining stable vitals

Time bonuses for fast operations

Lose points for:

Using wrong tools

Missing target zones

Patient deterioration

Difficulty Levels

Easy — Slower bleeding, larger target zones, no cardiac arrest, 80% score multiplier

Normal — Balanced, ~55% chance of cardiac arrest, 1x score multiplier

Expert — Realistic complications, guaranteed cardiac arrest, tighter zones, faster bleeding, 1.4x score multiplier

Procedural Patient Generation

Every operation features a randomized patient with:

Unique name (diverse international names: Maria Costa, Omar Ahmed, Yuki Tanaka, etc.)

Age, sex, weight, blood type

Allergies (penicillin, latex, iodine, etc.)

Case history/presenting complaint

Baseline vital signs

No save system — every game is a fresh, permadeath surgical challenge.

Visual & Audio Design

Photoreal Aesthetic

AI-generated surgical photography assets

AAA-quality UI with glowing teal accents and dark medical palette

Animated ECG strips, vital monitors, and OR environment

Canvas-based rendering with particle effects (blood spray, sparks, energy bursts)

Professional Audio

Voice announcements — 29 procedural voice lines guide you through each step

Procedural Web Audio for ambient OR sounds, monitor beeps, tool SFX

Dynamic heart rate beeping synchronized to patient vitals

Flatline alarm for cardiac arrest

Tool-specific sounds (saw buzzing, laser hum, forceps clamp, defib charge/shock)

Controls

Mouse: Click/drag to operate with selected tool

Number Keys 1-9: Quick-select tools from toolbar

P / ESC: Pause game

B: Toggle blood effects on/off

Game Flow

Main Menu — Sleek, photoreal medical interface with background slideshow

Operation Setup — Select procedure, generate/reroll patient, choose difficulty

Surgery — Complete 4-7 step procedure while managing vitals and emergencies

Result Screen — Win/lose outcome with detailed stats and final score

Win/Lose Conditions

Victory: Complete all surgical steps with the patient alive and vitals stable

Failure:

Blood loss reaches 100% (exsanguination)

Oxygen saturation drops below 42%

Cardiac arrest countdown expires

Procedure time runs out (140-200 seconds depending on surgery)
