[🧪] Ragdoll Research
01
Getting started
Step
In shortYour first kill unlocks your first badge and opens the door to everything else in the game.
When you load in, a ragdoll is right in front of you. Attack it and you earn the First Kill badge. From there, the game is yours to explore — weapons, mutations, vehicles, and tall buildings are all waiting.
Attack a ragdollhit the first one you see to unlock the First Kill badge.
Try different weaponsthe game lets you shoot, slice, bite, and inject, so test each method.
Inject a mutationinject a ragdoll to add a new entry to your Journal.
Use the environmentthrow ragdolls off buildings or put them in front of a car to see the physics engine do its thing.
Check your Journalevery new mutation you inject adds a record.
In shortThese badges require specific actions rather than raw kill counts.
None of these three badges come from grinding kills. Each one asks you to do something deliberate, and all three unlock automatically the moment you meet the condition.
Tips worth knowing
Bin Day — climb to the top of the office building, then throw a ragdoll so it lands in the bin at street level.
The Door... — feed the entity behind the door a ragdoll. Once you do, the badge pops.
Meet Your Maker — be in the same multiplayer lobby as the game owner.
05
Mutations and the Journal
Summary
In shortEvery mutation you inject on a ragdoll leaves a permanent record in your Journal.
Injecting mutations is one of the core loops in Ragdoll Research. Each injection changes the ragdoll in some way, and the result gets logged as a new Journal entry.
Inject to discover each mutation you apply unlocks a fresh Journal entry.
Fictional-character powers some equipment lets you use abilities drawn from famous fictional characters.
06
Getting the most out of the physics
Tips
In shortHeight, weight, and speed all change what happens to a ragdoll.
The physics engine reacts differently depending on how you set up each experiment.
Tips worth knowing
Throw from higher up to produce bigger impacts when ragdolls hit the ground.
Stack heavy objects on top of a ragdoll to watch the squish physics in action.
Use a car as a crash-test rig by placing a ragdoll in its path and driving into it.
