Ventilation Shafts
Vertical passages that move fresh air underground and exhaust stale air from tall buildings.
Ventilation shafts, also known as airshafts or vent shafts, are vertical passages used in mines and tunnels to move fresh air underground and to remove stale air. In architecture, an airshaft (also called a lightwell) is a small, vertical space within a tall building that permits ventilation of interior spaces to the outside. The floor plan of a building with an airshaft is often described as a "square donut" shape. Alternatively, an airshaft may be formed between two adjacent buildings. Windows on the interior side of the donut allow air from the building to be exhausted into the shaft, and depending on the height and width of the shaft, may also allow extra sunlight inside.

Lore & Background
In subterranean civil engineering, ventilation shafts are essential for moving fresh air into mines and tunnels while removing stale air. In architecture, the airshaft (or lightwell) is a small vertical space within a tall building, often creating a "square donut" floor plan. Windows on the interior side of the donut exhaust air into the shaft, and depending on the shaft's height and width, may also let in extra sunlight. An airshaft can also be formed between two adjacent buildings.
In Their Own Story
The shaft rose vertically through the building's core, a narrow passage of still air. On the interior side of the donut-shaped floor plan, windows opened into the shaft, allowing stale air from offices and apartments to be exhausted upward. Depending on the height and width of the shaft, some sunlight might filter down, casting a dim glow on the brick walls. Below, in the tunnels and mines, similar shafts pulled fresh air down and pushed stale air out, keeping the underground workable.
Reader's Guide
When exploring a building with an airshaft, look for the "square donut" floor plan—the shaft is the hollow center. Windows on the interior side of the donut are your key to ventilation; they exhaust air from the building into the shaft. The shaft's height and width determine how much extra sunlight reaches those interior windows. In underground civil engineering, ventilation shafts are vertical passages that move fresh air into mines and tunnels and remove stale air. They are also called airshafts or vent shafts.

Frequently Asked Questions
Who are Ventilation Shafts?
Ventilation shafts are not characters or entities within the game; they are architectural structures found inside the facility. They function as environmental passages rather than sentient beings with personal identities.
What is the role of Ventilation Shafts?
Their primary purpose is to enable stealth traversal by allowing the boy to move through confined spaces unseen. These areas are essential for bypassing guards and navigating restricted sections of the industrial complex.
How does the story of Ventilation Shafts end?
As inanimate objects, ventilation shafts do not have a personal narrative or conclusion independent of the player's journey. They remain static environmental features until the protagonist completes the associated level.
Why are Ventilation Shafts important to gameplay?
These passages provide critical access points that cannot be reached through normal doors or hallways. They force players to utilize crawling and hiding mechanics to progress safely through hazardous areas.
What atmosphere do Ventilation Shafts create?
They contribute significantly to the game's oppressive mood by creating claustrophobic, dimly lit environments for navigation. This design emphasizes vulnerability and tension while avoiding direct confrontation with enemies.
