About SCP – Containment Breach
SCP – Containment Breach is a free survival‑horror title built in Blitz3D. Players assume the role of a disposable Class D test subject inside a secret Foundation containment site that suffers a massive breach. The core objective is to survive the roaming SCP entities and find an exit, while optional document hunting reveals the cause of the incident.
The game features a procedurally generated layout, a mandatory blinking mechanic tied to the iconic SCP‑173, and a variety of obstacles such as gas, locked doors, and timer‑controlled gates. Community‑driven updates add DirectX 9 support, Steam integration, and a bundled room editor for custom content.
01 / THE GUIDE
Core Gameplay Mechanics
The player moves through a containment complex as a Class D subject, aiming to escape alive. Survival depends on avoiding SCP entities, managing the forced blink cycle, and interacting with environmental hazards like decontamination gas.
Document collection is optional but provides narrative context and clues about the breach. The game runs in single‑player mode and allows saving at any point, letting players pause and resume their run.
- Observe gas‑filled areas before entering; they increase blink speed.
- Take note of document locations early to reduce backtracking.
02 / THE GUIDE
Procedurally Generated Map
Each playthrough creates a new layout of rooms, doors, and SCP placements, ensuring no two runs are identical. This randomness means players cannot rely on memorized routes and must adapt to new configurations each time.
The map generation also determines where keycards and access codes appear, influencing which doors can be opened without prior knowledge of the layout.
- Treat each new corridor as unknown; proceed cautiously.
- Keep an eye on the map when it appears to plan escape routes.

SCP‑173 and the Blink Mechanic
SCP‑173 is a concrete sculpture that kills instantly when not observed. Its weakness is that it freezes while any player is looking at it, making eye contact a crucial survival tool.
The game forces the character to blink at regular intervals, and a blink occurring near SCP‑173 can result in an instant death. Managing blink timing is therefore essential when the statue is nearby.
- Keep your view on SCP‑173 whenever possible to prevent movement.
- Watch the blink timer and plan safe pauses before it expires.

Locked Doors and Access Requirements
Many doors in the facility are locked and require a keycard with sufficient security clearance or a specific access code to open. These items are scattered throughout the map and must be collected to progress.
Some doors operate on timer switches, opening only for a limited period after activation. Players must time their passage accordingly to avoid being trapped.
- Collect any keycards you find; they may be needed for doors requiring sufficient security clearance.
- When encountering a timer door, note the open duration before rushing through.

Modding Support and Room Editor
The release includes the Containment Breach Room Editor Extended (CBRE‑EX), allowing players to create and share custom rooms. This tool is bundled with the game and integrates with Steam Workshop for easy distribution.
Community‑created fixes and quality‑of‑life improvements are delivered through the same Steam integration, keeping the classic experience compatible with modern systems via DirectX 9 support.
- Use the editor to experiment with layout changes before publishing.
- Browse the Workshop for maps that adjust difficulty or add new SCPs.
