Building Horror Games Fast with Strafekit's Modular Assets

February 10, 2025

The air hangs thick and still. A single, bare bulb flickers overhead, casting grotesque shadows that dance with every strained breath. The rusted metal groans as you squeeze through the narrow passage, the walls pressing in on you. Every drip and scuttle echoes unnervingly close, a constant reminder that you are trapped. Welcome to confined horror, where the environment itself is your enemy.

For indie developers crafting terrifying horror experiences, time and resources are often in short supply. This article shows you how to use Strafekit's extensive library of modular assets to quickly create compelling, confined horror environments, saving you time and resources. We’ll explore specific techniques and asset combinations to build unforgettable settings that will leave your players breathless with dread.

Think of the tight corridors of the Nostromo from Alien, the labyrinthine depths of Amnesia: The Dark Descent, or the eerie, confined spaces of P.T. These games masterfully use limited space to amplify fear and vulnerability. This article builds out the Strafekit content pillar and lays the groundwork for a sub-pillar focused on modular level design, offering insights that will benefit indie developers looking to maximize their efficiency and creative output.

Understanding the Power of Confined Horror Environments

Environments in horror games aren’t just backdrops; they’re active participants in creating fear and suspense. A well-designed, confined horror environment:

Amplifies Claustrophobia: Tight spaces heighten the sense of being trapped and vulnerable, making every creak and shadow a potential threat.
Creates a Sense of Impending Doom: Limited visibility and winding paths make players anticipate threats around every corner, keeping them on edge.
Focuses Player Attention: Confined spaces force players to pay attention to details, amplifying the impact of subtle environmental cues and jump scares.

Crafting Claustrophobic Nightmares with Strafekit

Strafekit provides an extensive selection of assets to construct confined horror environments quickly and efficiently, with modular kits at the forefront. Here’s how to take full advantage:

Industrial/Mechanical Confinement

For a gritty, industrial horror setting, the Modular Puzzle kits offer a wealth of options. Imagine a puzzle where the player must reroute power through a series of damaged conduits to unlock a door, all while being pursued by a monster.

Create a dead end using three Modular Puzzle: Conduit Standard (Straight) pieces, then add a Modular Puzzle: Conduit Standard (End) with flickering lights above, creating a sense of being trapped.
Build narrow, twisting corridors by arranging the Modular Puzzle: Conduit Standard (Straight) and Modular Puzzle: Conduit Standard (Corner) assets. Vary the height and direction of the conduits to create a sense of disorientation. Place a straight conduit section on the floor, then immediately transition to a corner piece angled upwards, forcing the player to crouch and then stand, disrupting their sense of balance and spatial awareness.
Emphasize the feeling of being hemmed in by placing these conduits close to the player’s path. Sharpen the textures on these modular kit pieces using Enhance, bringing out the grime and detail of the metal, and creating a more visceral sense of decay. Focus particularly on enhancing the rust and dirt details on the edges of the modules to highlight their age and disrepair.
Add the sounds of dripping water from the Sounds of Water (77 unique water foley sounds) pack near the Modular Puzzle: Conduit Standard (End) to create a sense of a leaking, abandoned system. In the distance add ambient city noises from the sounds from the city (54 unique foley sounds).

Cramped Residential Decay

Create a sense of unease and claustrophobia by building decaying, cramped residential spaces using repurposed architectural elements.

Start with the Uluwatu - Modular Balinese Architecture Kit and reconfigure it to create tight, interconnected rooms. Instead of using the kit to build grand, open structures, focus on creating small, claustrophobic spaces. Use walls and ceilings to lower the perceived height of the rooms, making the player feel cramped and confined. Use the original architectural intention to mislead the player, as what was once beautiful is now used for horror.
Combine the kit with Geometric Rubble Props to create a sense of collapse and disuse. Position rubble props to block doorways or narrow corridors, forcing players to navigate carefully and heightening their sense of vulnerability. Create a sense of structural instability by clipping rubble pieces through walls and floors.
Optimize texture sizes with Transform to maintain performance in these detail-rich, confined environments. Reduce the texture resolution of less-visible elements, such as ceiling panels or distant walls, to save memory without significantly impacting visual quality.
Scatter furniture and personal items to hint at the lives that once occupied these spaces. A child’s toy lying amidst the rubble can hint at a tragic event.
Use Symphony to generate a low, ominous drone with unsettling metallic scrapes to underscore the environment’s decay and amplify player anxiety. Experiment with dissonant chords and atonal melodies to create a sense of unease. Add foley sounds of wind and creaking wood to evoke a sense of isolation.

Other Environment Examples

The modularity of Strafekit makes it easy to create a variety of confined horror environments. Use the Uluwatu - Modular Balinese Architecture Kit to create a sense of wrongness, by making a space that should be open and airy feel claustrophobic instead. Use the Modular Puzzle kits to construct a series of interconnected tunnels, each with its own unique puzzle to solve. The possibilities are endless.

Lighting for Maximum Dread

Lighting is paramount in confined horror, guiding the player’s eye and creating a sense of unease.

Use dynamic lighting to cast long, eerie shadows down narrow corridors, drawing the player’s eye to potential threats. Make sure your shadows are sharp and defined, emphasizing the geometry of the environment and creating stark contrasts. For example, place a flickering light source at the end of a corridor created with the Modular Puzzle kit, casting long, distorted shadows that obscure the player’s path.
Create pools of darkness to conceal threats and create a sense of the unknown. Use a limited number of light sources to create a high contrast between light and shadow.
Use colored lighting to create different moods. Red lighting can suggest danger or violence, while blue lighting can create a sense of coldness and isolation.

Sound Design for Maximum Dread

Sound is crucial for building tension in confined spaces. Here’s how to integrate specific sounds with your modular environments:

In an industrial corridor, the sound of dripping water from the Sounds of Water (77 unique water foley sounds) pack in a confined, stone corridor can amplify the feeling of dampness and decay. Pan the dripping sound slightly to the left of the player, creating a sense of unease and implying a leak just out of sight.
In a forest environment, use the Sounds of the Forest (66 unique nature foley sounds) pack to introduce subtle, unsettling nature sounds, such as rustling leaves or distant animal cries, to heighten the sense of isolation.
Use echoing Footstep Foley Sound Effects to suggest the presence of a larger, empty space beyond the player’s immediate surroundings. Vary the footstep sounds based on the surface the player is walking on to increase realism.
Select music that enhances the feeling of dread and confinement. Strafekit has royalty-free horror music to use in your game: Sinister Depths / Horror for underground bunkers, Chainsaw Waltz / Horror, Possession / Horror, Leave Now / Horror, Them / Horror, Witch Child / Horwror, Haunting Shadow / Horror for dilapidated mansions, Sole Maniac / Horror, Harvest Night / Horror, and Glimmer / Horror. Layer these tracks subtly, allowing the atmosphere to build gradually.

Maximizing Immersion Through Environment Design

Beyond just populating your environments with assets, consider these tips to maximize the sense of immersion, always with a focus on how they enhance your modular environments:

Environmental Storytelling: Use Strafekit’s assets to tell a story about the environment’s past. Scatter Geometric Rubble Props around a ruined building to create a sense of decay and abandonment. A child’s toy lying amidst the rubble can hint at a tragic event. The modular nature of Strafekit’s kits lets you quickly iterate on these storytelling elements. Swap out different props and rearrange them to create new narratives and emotional impacts.
Restricted Visibility: Use fog, darkness, and narrow corridors to limit the player’s field of view, creating a sense of claustrophobia and vulnerability. For information about adding fog in Unity, read How to Add Fog in Unity. Use fog to obscure the ends of corridors in your modular kit environment, creating a sense of paranoia. Experiment with different fog colors and densities to create a variety of moods.
Subtlety: Sometimes, what you don’t show is more effective than what you do. Imply the presence of unseen entities through sound cues or subtle environmental changes. Refer to Level Design Tips and Best Practices

Troubleshooting Common Problems

Creating confined spaces can present unique challenges. Here are a few common problems and solutions:

Camera Clipping: Prevent the camera from passing through walls by adjusting the near clip plane on the camera or by implementing a camera collision system.
Player Movement Issues: Ensure the player can navigate tight spaces smoothly by adjusting the character controller’s radius and height, and by carefully designing the environment to avoid sharp corners or unwalkable areas. With modular kits, it’s easy to identify and adjust problem areas. Simply swap out offending modules for alternatives or adjust their placement to create a smoother path for the player.
Performance Issues: Optimize your environment by using efficient models and textures, and by using techniques like occlusion culling to hide objects that are not visible to the player. Ensure consistent texture scaling across different modular pieces to avoid visual discrepancies and improve performance. Use LOD (Level of Detail) groups to reduce the polygon count of distant objects, further optimizing performance in confined spaces.
