Injured Limbs, Lost Abilities

Hurt legs can't run, hurt hands can't aim: where you're hit decides what you can do.

01The core loop

Action → feedback → next choice
  1. 01A body part is hurt
  2. 02Linked abilities drop
  3. 03Adjust roles or tactics
  4. 04Heal or replace the limb

↻Feedback changes the situation — the next round starts from there.

Walk through one round

A simplified design example. Situations and numbers illustrate the mechanic, not exact rules from a reference game.

  1. T1

    Turn 1 · The situation

    The squad's shooter has a badly hurt right arm, accuracy −40%.

  2. T2

    Turn 2 · The player chooses

    Move him to guard duty and bring a melee fighter forward.

  3. T3

    Turn 3 · The feedback

    Front-line firepower drops, but the shooter is back to 80% in three days.

  4. T4

    Turn 4 · The next decision

    Save up for a bionic arm to solve it for good.

How it plays

Damage lands on specific parts, each tied to abilities: legs for movement, hands for manipulation. Severe damage can disable or sever a part, requiring long recovery or artificial replacement.

What the player weighs

  • Keep the injured working or bench them
  • Wait to heal or pay for a prosthetic

03One mechanic, different implementations

Kenshi
K

Kenshi

P1

Limbs and torso have separate health; limbs can be crippled or severed and replaced with robotic ones of varying quality, sometimes better than the original.

RimWorld
R

RimWorld

P2

Damaged parts reduce capacities such as moving and manipulation, and missing parts can be replaced with peg legs, prosthetics or bionics.

The difference worth noticing

In Kenshi a lost limb is often a power upgrade path; in RimWorld it is a colony burden managed with medicine and resources.

Case notes are Yoroll editorial summaries; rules may change between versions.

04What could you combine?

Fusion · Original design proposal · not an existing feature
Injured Limbs, Lost AbilitiesSurvival & needs+

Feed limb injuries into cover and flanking: a leg-hurt unit cannot dash between cover, so teammates must flank to protect them.
