# Horror and tension

Horror builds decisions around limited certainty, defensive means and safe recovery time. Each overview separates player actions, state changes and alternative rules. Examples are hypothetical design scenarios, not claims about a named game. A prototype check states an observable question for the next iteration. Existing detailed references remain separately linked from the direction map.

## Mechanics and variants

<a id="mechanics"></a>

### 1. Survival horror and limited defenses

<a id="t210"></a>
id: t210
canonicalId: horror-tension--t210
url: https://gamemechanics.pro/en/mechanics/horror-tension/#t210

Limited defenses turn threatening encounters into choices between resistance, avoidance and spending a scarce reserve.

#### Mechanic variants

<a id="t210-variants"></a>
- Ammunition limits direct confrontations. <a id="t210-v1"></a>
- Gunfire noise attracts additional threats. <a id="t210-v2"></a>
- Consumables create a brief safety window. <a id="t210-v3"></a>
- Injuries reduce options for subsequent escape. <a id="t210-v4"></a>

Design example: The last round clears a passage but attracts an opponent from another wing.

Prototype check: Test completion with the minimum viable supplies, including avoidance of optional combat.

### 2. Hiding and escaping from threats

<a id="t211"></a>
id: t211
canonicalId: horror-tension--t211
url: https://gamemechanics.pro/en/mechanics/horror-tension/#t211

Hiding preserves uncertainty about position, while escape requires breaking contact and finding a safe next move.

#### Mechanic variants

<a id="t211-variants"></a>
- Hiding blocks vision but does not remove noise. <a id="t211-v1"></a>
- Held breath limits motionless hiding time. <a id="t211-v2"></a>
- Decoys shift attention to another room. <a id="t211-v3"></a>
- Moving between shelters creates exposure windows. <a id="t211-v4"></a>

Design example: A player hides behind shelving and moves under machinery noise to reach a door.

Prototype check: Test that searching follows threat observations rather than permanent knowledge of player position.

### 3. Psychological horror and uncertainty

<a id="t212"></a>
id: t212
canonicalId: horror-tension--t212
url: https://gamemechanics.pro/en/mechanics/horror-tension/#t212

Uncertainty requires interpreting incomplete signals while preserving doubt without arbitrarily invalidating every rule.

#### Mechanic variants

<a id="t212-variants"></a>
- Conflicting signals permit several explanations. <a id="t212-v1"></a>
- Repeated scenes alter one meaningful detail. <a id="t212-v2"></a>
- Limited sources have testable reliability. <a id="t212-v3"></a>
- Consequences distinguish threats from appearances. <a id="t212-v4"></a>

Design example: Footsteps may be echoes, but a later open door provides independent evidence of a presence.

Prototype check: Test whether careful observation remains useful after unreliable perception has been revealed.

### 4. Anomaly hunting and detecting changes

<a id="t213"></a>
id: t213
canonicalId: horror-tension--t213
url: https://gamemechanics.pro/en/mechanics/horror-tension/#t213

Players compare a familiar place with its current state and decide whether a change is a meaningful anomaly.

#### Mechanic variants

<a id="t213-variants"></a>
- Baseline scenes provide time to learn normality. <a id="t213-v1"></a>
- Object changes violate a learned expectation. <a id="t213-v2"></a>
- Reporting rules set the cost of false alarms. <a id="t213-v3"></a>
- New cycles test a different feature type. <a id="t213-v4"></a>

Design example: An evacuation arrow changes direction on a familiar floor while the furniture remains unchanged.

Prototype check: Test anomaly visibility across resolutions and exclude incidental lighting variation from valid answers.

### 5. Pursuers and adaptive behavior

<a id="t214"></a>
id: t214
canonicalId: horror-tension--t214
url: https://gamemechanics.pro/en/mechanics/horror-tension/#t214

A pursuer selects behavior from observations and memory, making habitual escape methods less reliable through adaptation.

#### Mechanic variants

<a id="t214-variants"></a>
- Memory raises interest in a previously used hiding place. <a id="t214-v1"></a>
- Hearing creates a last known search region. <a id="t214-v2"></a>
- Flanking changes routes when a direct path closes. <a id="t214-v3"></a>
- Adaptation limits preserve counterplay. <a id="t214-v4"></a>

Design example: Repeated closet escapes make a pursuer check closets more often without knowing the correct one.

Prototype check: Test learning from available observations only and preserve another viable way to escape.

### 6. Sanctuaries, respite and tension cycles

<a id="t215"></a>
id: t215
canonicalId: horror-tension--t215
url: https://gamemechanics.pro/en/mechanics/horror-tension/#t215

Respite reduces immediate risk and restores planning time; leaving safety reintroduces uncertainty.

#### Mechanic variants

<a id="t215-variants"></a>
- Clear boundaries separate shelter from danger. <a id="t215-v1"></a>
- Limited supplies prevent free complete recovery. <a id="t215-v2"></a>
- Short safe loops provide time to interpret events. <a id="t215-v3"></a>
- Breached sanctuaries signal a changed rule beforehand. <a id="t215-v4"></a>

Design example: A lit control room allows map reading, but fuel for the next excursion remains limited.

Prototype check: Test recognition of respite and the ability to stop a session comfortably inside a sanctuary.

### 7. Sensory limitations and incomplete information

<a id="t216"></a>
id: t216
canonicalId: horror-tension--t216
url: https://gamemechanics.pro/en/mechanics/horror-tension/#t216

A constrained perception channel changes information gathering, increasing the value of available signals and verification.

#### Mechanic variants

<a id="t216-variants"></a>
- Light cones restrict the visible sector. <a id="t216-v1"></a>
- Noise masks a quiet approaching threat. <a id="t216-v2"></a>
- Instruments display traces with a delay. <a id="t216-v3"></a>
- Alternative channels preserve essential accessibility. <a id="t216-v4"></a>

Design example: An instrument detects motion behind a wall but updates slowly and shows no exact creature shape.

Prototype check: Test essential signal readability with accessibility settings and decorative effects disabled.

- [Frictional Games: Amnesia](https://www.amnesiagame.com/)

### 8. Cooperative horror and group risk

<a id="t217"></a>
id: t217
canonicalId: horror-tension--t217
url: https://gamemechanics.pro/en/mechanics/horror-tension/#t217

Group risk arises from split tasks, mutual dependence and limited communication while under threat.

#### Mechanic variants

<a id="t217-variants"></a>
- Splitting speeds objectives at the cost of support. <a id="t217-v1"></a>
- Communication noise exposes the team. <a id="t217-v2"></a>
- Rescue forces a shared route change. <a id="t217-v3"></a>
- Shared resources require coordinated spending. <a id="t217-v4"></a>

Design example: One participant starts a basement generator while others hold a door and report the approaching threat.

Prototype check: Test recovery after a disconnect and useful actions for a participant left alone.
