Self-sealing Airlocks Revived (U59 Fix)

Mastering Your Colony’s Atmosphere with Self-Sealing Airlocks

Managing the delicate atmospheres within your Oxygen Not Included colony is paramount to survival and prosperity. While standard doors offer basic passage, they often fall short when it comes to preventing unwanted gas or liquid migration. This is where the Self-Sealing Airlocks Revived mod steps in, offering a crucial fix for an essential base-building mechanic.

The Problem with Standard Doors

In the base game, even when set to “Auto,” most doors allow for a subtle but significant exchange of gases and liquids. This necessitates the creation of complex and space-consuming “waterlocks” using precisely placed liquid to create a seal. These double-door systems, while functional, add to the micro-management burden and can be an inefficient use of your duplicants’ time and your colony’s resources.

How the Mod Enhances Your Base

Self-Sealing Airlocks Revived directly addresses this limitation. When applied to specific door types and set to “Auto,” these doors will now function as true airlocks, completely preventing the flow of both liquids and gases. This simple yet powerful change streamlines base design and significantly improves atmospheric control. You can finally say goodbye to the need for cumbersome double-door waterlocks.

Key Features and Affected Doors

This mod focuses on bringing back a vital functionality that was broken in recent game updates. Here’s what you need to know:

• Complete Sealing: Doors affected by this mod will form an airtight and liquid-tight seal when set to “Auto.”
• Streamlined Base Design: Eliminates the need for complex double-door waterlock systems, saving space and resources.
• Fix for U59 and Later: This version specifically recompiles the original mod to work with the latest game builds (U59-737790 and beyond), resolving critical errors that prevented it from functioning.
• Affected Doors: The Manual Airlock and Mechanized Airlock gain true self-sealing capabilities.
• Pneumatic Door Remains Unaffected: The cheaper, less effective Pneumatic Door is intentionally left as is, preserving the option for a basic, leaky passage if desired.

By implementing this mod, you can achieve greater efficiency in your base layout and maintain a more stable and controlled environment for your duplicants, ensuring their continued success in the harsh world of Oxygen Not Included.
