Mods

User guides for X4 Foundations mods. Each page covers:

• Short description — what the mod does at a glance
• Installation & configuration — requirements, install options, in-game setup
• Known conflicts — mods that don’t play well together (if any)
• Deep dive — long-form breakdown of the mod’s features and game mechanics

We start with the mods we currently maintain (all X4 9.0-compatible, actively updated), and are gradually expanding to cover other popular community mods.

Mods we maintain (v2.0.0, X4 9.0)

Core dynamic-universe stack

• DeadAir Scripts (mlog4 fork) — Dynamic War, Xenon Evolution, Jobs Expeditions, Station Fill, and more. Standard variant with DA custom wares.
• DeadAir Scripts (No DA Wares fork) — Same features, custom wares stripped. For VRO / X4-Reemergence / vanilla-economy players.
• DeadAir Economy Overhaul (mlog4 fork) — Economy tuning, station enhancements, 3 custom wares. Standard companion to DA Scripts.
• DeadAir Economy Overhaul (No DA Wares fork) — Same tuning without custom wares. Clean pairing with VRO or vanilla economy.

Modded-faction compatibility patches

• Apus Compat Patch — Full DA integration for Apus Stellar Treaty faction.
• ETW Compat Patch — Full DA integration for all 3 Eternal Twilight Expansion factions.

Quick pick guide

Playing vanilla X4 9.0 with the DA economy layer (custom wares included): → DA Scripts (standard) + DA Eco (standard)

Playing with VRO 5.01 or X4-Reemergence (when available): → DA Scripts (No DA Wares) + DA Eco (No DA Wares)

Also running Apus Stellar Treaty? → Add Apus Compat Patch

Also running Eternal Twilight Expansion? → Add ETW Compat Patch

All combinations tested via 5.5-hour multi-mod soaks on X4 9.0. Zero errors in the mod namespace.

We’re gradually adding user guides for other popular mods that work on X4 9.0. Expected next:
