# Truth Revelation Mechanic

## Mechanic Definition

An item or action reveals hidden truth—disguising what's false, exposing hidden identity, or showing what lies beneath the surface. The solution is not combat or force but *seeing through* deception. The truth itself is the key that unlocks the puzzle.

This differs from "evidence collection" puzzles: the item doesn't just *prove* something, it actively *shows* something.

## Information Architecture

**Conveyance Method**: Item-based revelation
- Player obtains a "revealing" item through gameplay
- Using the item on a target reveals hidden information
- The reveal is diegetic—within the game world, not a UI popup

**Player Action Pattern**:
1. Obtain revelation item through normal gameplay
2. Identify suspect/obstacle that might be disguised
3. Use revealing item on target
4. Information revealed → player knows truth
5. Use truth to solve puzzle (unlock path, prove guilt, etc.)

**Core Mechanic**: The puzzle isn't about finding evidence—it's about revealing what's hidden. The item is a probe, not a weapon.

## Design Rationale

- Rewards observation—player must suspect something is hidden before investigating
- Creates dramatic reveals—unmasking is inherently theatrical
- Avoids violence—solution is cognitive, not confrontational
- Integrates with narrative—revealing truth advances the story

## Why It's Effective

The reveal moment is satisfying because it's active discovery, not passive proof-gathering. The player uses a tool to learn something, not collects documents to prove something.

## Mechanic Variations

| Variation | Revelation Method | Information Revealed |
|-----------|-------------------|---------------------|
| Optical | Special item shows true form | Identity, disguise |
| Chemical | Substance reveals hidden marks | Truth, lies, secret writing |
| Physical | Object breaks concealment | Hidden rooms, mechanisms |
| Temporal | Time reveals truth | History, past events |
| Emotional | Truth triggers response | Deception, intentions |

## Generic Example Structure

**Goal**: Identify the [Imposter/Truth/Hidden Thing]

**Information Flow**:
- Player obtains [Revealing Item] through normal exploration
- Player suspects something is not as it seems (through dialogue contradictions, visual anomalies)
- Player uses [Revealing Item] on [Suspect/Object]
- Game shows what's actually there (not what appears)
- Player uses revealed truth to solve puzzle

**The puzzle**: Player must both obtain the revealing item AND correctly identify what to use it on.

## Adventure Game Implementation

Limited actions drive this puzzle:
- LOOK at suspects carefully—visual anomalies suggest hidden truth
- TALK to NPCs—contradictions in dialogue suggest deception
- USE revealing item on suspected target
- The solution is the revealed truth, not the item itself

This puzzle tests: "Can I identify what's hidden and use the right tool to reveal it?"
