What Is the Trauma Lab Game?
Trauma Lab describes itself as "an anatomy and physics sandbox." You get a single test subject in a lab and a huge set of tools: shoot, stab, burn or poison him, then look under the skin to see exactly what happened — or put the weapons down and try to save him.
What makes the Trauma Lab game different from a typical ragdoll sandbox is how deep the simulation goes:
- Ballistics that follow the bullet. Every shot is traced through what it hits, from a fractured rib to a perforated lung to a severed aorta. Ammo types include FMJ, hollow point, AP and fragmenting rounds.
- X-ray layers. Peel back skin, muscle, organs, arteries and veins, bones and nerves to inspect the damage. The X-ray view dims the room so organs and bullet paths stand out.
- Live vitals. Heart rate, blood pressure, SpO₂ and blood loss update in real time on the patient monitor. Shock, cardiac arrest and bleed-out all play out on screen.
- Medicine and surgery. Bandages, tourniquets, drugs and chemistry, plus a Simple or Complex surgery mode with stitches, bone plates, suction and blood top-ups.
- Powers. Lightning, fireball, freeze, acid, black hole and more.
- Scenes. The default test chamber, plus a trauma bay, field hospital, castle and battlefield, each with its own lighting.
The game runs on the developer's own HTML5 engine, so it works in a desktop or phone browser. It is still in development and updates arrive very quickly — it went from v1.06 at launch to v1.19 within two days. The developer lists AI assistance for code, graphics and sounds on the itch.io page.
Content warning: this game contains graphic injury, blood and medical detail and is intended for players 18+.
How to Play Online
To play online, press Play above. The browser version is the same build that runs on itch.io, so there is nothing to install. Use the Fullscreen button (or F11 on PC) for the best view. On a phone, the game switches to a dedicated phone layout with bigger vitals and pinch-to-zoom.
Default PC controls (you can rebind them in Options):
| Key | Action |
|---|---|
| 1 / 2 / 3 / 4 / 5 | Hand tools · Weapons · Props · Medicine · Powers |
| Q / E | Previous / next tool in the tab |
| F | Switch tool mode (slash/stab, semi/auto…) |
| X | X-ray |
| Space | Pause / play |
| = / − / 0 | Zoom in / zoom out / fit to screen |
| H | Challenge: Keep Him Alive |
| O | Options |
Tips: if the game lags, lower the gore level in the Options menu — that is the developer's own advice. If you want it bloodier, the developer recommends the extreme gore setting instead. There is also a built-in Russian language option that switches on automatically when your browser is set to Russian.

Game Modes: Sandbox and Keep Him Alive
- Sandbox — free play with every weapon, tool, chemical and power. Experiment, inspect wounds with X-ray and watch the vitals react.
- Keep Him Alive — a challenge mode with 10 real emergencies that you treat with the Medicine tab only. Press H to open it.
- Story mode — in development. The latest patch notes describe a three-room prototype with guards, cover and a sentry gun. New Story builds go to supporters and Discord playtesters first; the free build shows a teaser.
Keep Him Alive: All 10 Emergencies (Walkthrough)
Keep Him Alive uses the same physiology as the sandbox: bleeding, drugs, heart and lungs behave exactly the same. You win once the patient has been stable for 15 seconds in a row — bleeding controlled, blood pressure and oxygen holding. You lose if he dies, or if his systolic pressure stays under 60 mmHg for 6 seconds.
The table below lists every case in Trauma Lab v1.19 with the in-game hint.
| # | Emergency | Patient | What's wrong | How to save him (in-game tip) |
|---|---|---|---|---|
| 1 | Gunshot · thigh | Soldier, 24 | 9 mm round through the left thigh; femoral artery torn (up to ~1 L/min blood loss) | Tourniquet high on the thigh, pack the hole with gauze, then give blood. TXA (tranexamic acid) helps reduce bleeding deaths. |
| 2 | Sword cut · arm | Squire, 19 | Brachial artery cut in the inner upper arm | Tourniquet above the cut, then suture or clamp the vessel (Surgery). Replace lost blood. |
| 3 | Open fracture · shin | Motorcyclist, 31 | Tibia through the skin, shin artery torn, severe pain | Tourniquet above the knee, gauze and bandage, a bone plate (Ortho), morphine or ketamine for pain. |
| 4 | Heart attack · cardiac arrest | Man, 72 | Blocked coronary artery; rhythm collapses into VF | Defibrillate (VF is shockable). Adrenaline every few minutes; amiodarone after the 3rd shock keeps the rhythm stable. |
| 5 | Heart wall rupture · needs surgery | Woman, 78 | Dead heart muscle tore; blood leaking around the heart | Fluids and blood to buy time, then chest surgery to repair the heart. Defib if it fibrillates. |
| 6 | Opioid overdose | Man, 29, found unresponsive | Fentanyl stopped his breathing; pinpoint pupils | Naloxone reverses it within a minute — but it wears off sooner than fentanyl, so watch for him going under again. |
| 7 | Sleeping pills + alcohol | Woman, 45 | Benzodiazepine overdose on top of alcohol | Flumazenil reverses the benzodiazepine (can trigger seizures in long-term users). Alcohol has no antidote: wait it out. |
| 8 | House fire · cyanide | Firefighter, 38 | Hydrogen cyanide from burning plastics; SpO₂ looks fine but cells can't use oxygen | Cyanide antidote (hydroxocobalamin), plus fluids for blood pressure. |
| 9 | Snake bite | Ranger, 34 | Viper venom stops clotting and attacks vessels | Antivenom — but one dose too many can trigger anaphylaxis, so keep adrenaline ready. |
| 10 | Bee sting · anaphylaxis | Hiker, 26 | Airway swelling shut, vessels dilating | Adrenaline, then fluids for the pressure. |
General tips for Keep Him Alive: stop arterial bleeding first (bright red, pulsing), then replace blood, then deal with pain or the poison. Keep an eye on systolic pressure — falling under 60 mmHg is the fastest way to fail.
Medical disclaimer: this is a game. The tips describe in-game mechanics and are not medical advice.
Medicine, Drugs and Serums
The Medicine tab includes these drugs (doses as shown in the game): Adrenaline 1 mg, Amiodarone 300 mg, Atropine 1 mg, Fentanyl 100 mcg, Flumazenil 0.5 mg, Ketamine 50 mg, Midazolam 5 mg, Morphine 10 mg, Naloxone 0.4 mg, Paracetamol 1 g and Tranexamic acid 1 g, alongside tools like tourniquets, gauze, bandages, a defibrillator, fluids and blood.
Sandbox also has fantasy serums:
- Super serum — heals everything still inside the body (organs, brainstem, bones, wounds) and closes torn skin and muscle. It does not revive him and does not regrow limbs, as the developer confirmed in the comments.
- Ultra serum — revives and regrows: lost limbs and organs grow back, and organs that fell out are drawn back in.
- Super-soldier serum — also available in Sandbox.
- Inhibitor — stops everything: every drug, serum and poison.
Want the patient to sleep? The developer's answer: use ketamine.
Weapons, Powers and Tools
Weapons in Trauma Lab v1.19 include a pistol, revolver, SMG, rifle, assault rifle, shotgun, sniper rifle, crossbow, knife, machete, axe, baseball bat, grenade and C4, with several ammo types (FMJ, hollow point, AP, fragmenting). Arrows slice through tissue and often pass straight through. Powers include lightning, fireball, freeze, acid and a black hole. Use F to switch a tool's mode (for example slash or stab, semi or auto) and G to set melee strength.
