Anatomy Lab Chaos

Build absurd contraptions and test them on squishy dummies with a layered body model that reacts to every hit, a gore sandbox where the engineering is the game.

46% of Gore Sandbox games found an audience, yet few came out lately. 25 of 51 judged games reached 1,000 reviews, and 12 came out in the last three years.

What it feels like

You are a gleeful mad scientist who builds a machine, pulls the lever and watches the messy result unfold layer by layer.

The core loop

  • Build: Assemble a contraption from springs, blades, motors and ramps on the lab bench.
  • Test: Drop a dummy into it and trigger the machine.
  • Inspect: Replay the hit in slow motion and peel back the body layers to see what each part did.
  • Refine: Tweak the design to chase a bigger, funnier or more precise result.

One sitting

You open the lab, pick a test room and spend a while stacking contraptions, then share a favorite slow-motion replay. A sitting is a handful of builds, each testing a new idea.

What sets it apart

  • A layered body model you can inspect in replay, so each impact shows what happened inside, not just a splash.
  • A funny, cartoon tone with squishy dummies, closer to People Playground than to the grim realism of the misses.
  • Safe sharing from day one: contraptions are shared as plain data files with no scripts, answering the workshop fears in People Playground reviews.

The first playable

One room, one dummy with three body layers, and five parts (spring, blade, motor, hinge, weight). Build, trigger and replay in slow motion, and see whether people keep rebuilding.

Scope

  • One test room
  • One dummy with layered damage
  • Five build parts
  • Slow-motion replay
  • Several test rooms, some with open-world style hubs
  • A dozen more parts
  • Contraption sharing as data only, with no code
  • Controller and keyboard support

Art

Flat, bold 2D shapes with thick outlines and bright fluid colors, so a capsule reads clearly: one dummy, one big machine, one splash. Keep the animation in physics, not hand-drawn frames.

Risks

  • Hits lean on a shooter or open-world ingredient and this is a bench-based builder. Add a small explorable lab hub and an optional tool for shooting the dummies, so the shape still matches what hits share.
  • Mod and workshop security problems have hurt the biggest hit in this space. Share contraptions as data only, never run user code, and say so on the store page.
  • Misses lean on FPS and destruction, and the game could drift toward those. Keep the focus on physics and humor, and keep destruction to the dummy and its machines.

Price

$5 to $10: This band had the best share of games that found an audience, and the top sandbox hit sits here.
