Incompatible

Please note that while this list is frequently updated, it is by no means a be all to end all of incompatible mods. There could be some we have missed. If adding to this list please use the exact name of the mod, and only add mods if you've confirmed them to have issues on an otherwise-compatible setup.

FU Translation Mods / Language Translation Mods
Don't use them. None can keep up with us, and almost all are completely outdated or incompatible due to script related issues. They are not recommended and we will not help you debug them.

Frackin' Races
You don't need this if you're using FU. It's now included, and your game won't function if you have both installed.

zTarbound
This mod started in FU and has always been included with it. The zTarbound standalone page directly states that it cannot be used with FU individually as a result! Why didn't you read the mods page?

Usable With A Patch
These mods can be used so long as their external compatibility patch is installed as well.
 * Avali Triage (needs this patch)
 * Extended GUI (needs this patch)
 * Many Tabs (needs this patch)
 * Money Planet (needs this patch)
 * Better Shield Drones (Original breaks, use this version)

Potential Issues

 * Aimable Shields - All FU shields are already aimable
 * Augment Extractor - Already included in FU
 * Automation Aides - Shouldn't cause issues, but is already included in FU.
 * Classical Weaponry - Partially included in FU, and may break rapiers or other weapons.

 * FrackinUniverse Ground Seeders - Outdated, and FU already contains a more powerful tool to perform the same function.
 * Improved Containers - Outdated mod. Use Enhanced Storage instead.
 * Legacy Fuels - Duplicate plutonium issue
 * Madtulips Mod - FU already contains a BYOS system
 * Named Saplings - FU makes similar changes, and NS can't handle saplings crafted in the greenhouse.
 * Tier 9/Tier 10 ships - Breaks BYOS
 * TrueSpace - Some FU planets become too rare (hard to find). Breaks starting system generation (Moons, Deserts, and Forests are not guaranteed), which may result in an inability to obtain necessary materials.
