https://www.nexusmods.com/x4foundations/mods/540
v9. 0. 0. 6, 29 Jun 2026:
- New feature: Deactivating the mod from the Settings > Extensions menu deactivates the mod's scripts and zeroes its data. More information is in the "Uninstall" section.
- Note: Read the "Uninstall" section for important information on deactivating the mod and creating "clean" saves.
- Bug-fix: Teleporting to a station wasn't detected that prevented high-security rooms from getting locked.
- Bug-fix: The Transporter Room would fail if the internal data "directtarget" of a room is nil.
Mod effects
===========
- High-security rooms (Engineering Section, Security Office) are locked. Get access from a black marketeer in the sector.
- Buy black marketeer contacts in adjacent sectors from black marketeers.
Requirements
============
SirNukes Mod Support APIs mod (https://www.nexusmods.com/x4foundations/mods/503)
Kuertee's UI Extensions mod (https://www.nexusmods.com/x4foundations/mods/552)
High-security rooms are locked
==============================
To gain entry to the Engineering Sections or Security Offices of stations, access must be bought from a black marketeer in the sector.
Three types of accesses can be bought. And not all types are available.
1. A Transporter Room entry code. Use this immediately on the Transporter Room panel to gain entry to the high-security room.
2. A hacker who can hack the Transporter Room. Contact the hacker by scanning his Signal Comm. They will then hack the Transporter Room.
3. An operative who has access to the Transporter Room. Make contact with the operative and follow them through the Transporter Room.
Once unlocked, the key will be valid for only 10 minutes. (The key is stored in your PDA. If you abort the mission, you will lose the key.)
Note that if you find a mission NPC behind a locked room, they will be moved to an unlocked room AFTER you use the Transporter Room the first time. Usually, the mission NPC is moved AFTER you dock, but sometimes the mod doesn't find them at that time. Moving to another room will re-trigger the code that moves them to an unlocked room.
Additional Agent Effects mod
============================
Agents assigned to stations can unlock high-security rooms. More information is in the Additional Agent Effects mod read-me.
Black marketeer contacts
========================
Buy black marketeer contacts in adjacent sectors from black marketeers. You need to find a black marketeer before you can buy the mission signal of other black marketeers.

✨ Key Features
📊 Pros & Cons
✅ Pros
- Adds meaningful challenge and roleplay depth to station infiltration
- Three distinct access methods keep gameplay varied
- Active development with recent bug fixes (v9.0.0.6, June 2026)
⚠️ Cons
- Requires two external mods (SirNukes Mod Support APIs and Kuertee's UI Extensions) which adds setup complexity
- 10-minute key duration may feel restrictive for players who want longer access
- Potential compatibility risk with other mods that alter station interiors or black marketeers
For X4: Foundations players who want more challenge and immersion in station exploration, especially those who enjoy stealth and black market mechanics. Skip if you prefer unrestricted access to all station areas or don't want to manage additional mod dependencies.
