The core testing loop
The game provides no scripted story quests or stage progression. Instead, play revolves around an experimental cycle where every physical interaction updates your counters and provides diagnostic feedback.
| Phase | Input | Visible game reaction | Next player action |
|---|---|---|---|
| 1. Spawn | Press G |
A fresh ragdoll dummy appears on the pavement directly before you | Put weapons away or select an attack tool |
| 2. Impact | Left click or equip weapon | Dummy reacts dynamically: limps, crawls, or drops unconscious | Observe physical movement and posture |
| 3. Scan | Press V |
Body Scan overlay appears with bone status, heart rate, and blood | Check injury severity and cause of death |
| 4. Reset | Press R |
All downed and damaged dummies revive instantly; prompt shows All dummies revived |
Verify tracker progress and pick next test |
Understanding your head-up display
The interface keeps controls, weapon management, and objective tracking visible across four screen zones.
| Screen location | Interface element | Functional role |
|---|---|---|
| Bottom Center | R Revive | G Spawn | V Scan |
Primary action hotkeys for dummy management and physical diagnosis |
| Left Edge | Vertical menu: Shop, Tools, Lab, Lab Log |
Catalog access for gear unlocks, sandbox parameters, and event triggers |
| Top Right | Next: <Tool> N / M with green bar |
Cumulative knockout progress bar showing distance to the next weapon threshold |
| Bottom Strip | Hotbar slots (starts at 4 slots, scales to 9+) | Equipped weapons and utility gear mapped to number keys 1 through 9 |
Your first four minutes on the plaza
Follow this sequence to register your opening knockouts and verify basic controls.
- Check your opening inventory
Your hotbar begins with four default tools: Pistol in slot 1, Fists in slot 2, Fire Axe in slot 3, and Grenade in slot 4. The Tools panel marks this initial state asUNLOCKED 4/40. - Spawn a test subject
PressG. A dummy drops onto the concrete. If you stow your weapon and left-click the dummy, an on-screen prompt readsPut your tool away, then click a dummy to grab it. - Deliver targeted limb damage
Select the Fire Axe (3) or Pistol (1). Aim directly at the lower right leg and strike. The dummy stumbles and starts limping, matching the game's limb-damage physics model. Strike the same leg again until the bone gives way: the dummy collapses and begins crawling across the floor. - Inspect the injury with Body Scan
TapVwhile facing the fallen subject. A diagnostic card displays the dummy's name, active status, and remaining blood percentage, alongside an X-ray skeleton highlighting the broken limb in orange. - Score the knockout and reset the yard
Deliver a decisive blow to the skull. The status flips toOut coldorDead: bled out, and the tracker in the upper right ticks upward, readingNext: Bat 1 / 5. PressRto revive the yard and restore all subjects to full mobility.
Handling stalled progress or lost dummies
When physics glitches occur during heavy ragdoll testing, use these resets:
- Dummy launched out of testing bounds: When an explosion or high-velocity impact blasts a body across the map barrier, press
R. This immediately clears out-of-bounds entities and respawns active subjects. - Weapon fails to strike or swing: If clicking produces no swing animation, your character may be holding a grab state. Tap
Cor switch hotbar slots to clear active grip physics. - Tracker not advancing on down: If knocking a subject down fails to increment the
Next:counter, open controls and keybinds to confirm whether your attack registered as a full knockout or merely an incapacitating limb stun.
Advancing past the opening milestones
Once you register 5 knockouts, the Bat unlocks automatically in your Tools panel, expanding your blunt-force reach. From there, each additional knockout brings you closer to the Hand Cannon at 10 KOs and the Push Gun at 15 KOs. To understand the exact bone-breaking thresholds and diagnostic readouts behind each strike, explore our detailed breakdown of body damage and Body Scan.

FAQ
Does dying reset my progress toward the next weapon?
No. Your knockout total accumulates across your entire account lifetime. Falling off the map or getting caught in an explosion does not reduce your current counter.
Can I run this opening loop with other players on the server?
Recordings through 15 November 2026 show default public instances running with a server size of 1. While an Update 1 announcement mentioned multiplayer support, baseline sandbox play takes place in solo instances.
What happens if I close the game before reaching 5 knockouts?
Your earned knockouts remain saved to your profile data. When servers are accessible, you resume at the exact progress fraction displayed on your Next: widget.
Why does my hotbar only have four slots when videos show nine?
The hotbar scales dynamically as you acquire additional tools from the Tools panel. New players start with four assigned slots, while accounts with multiple unlocks show six, nine, or ten slots.
