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.

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 None can keep up with us, and almost all are completely outdated or incompatible due to script related issues.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.

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)
 * Many Tabs (needs this patch)

Having these installed may cause certain items to not appear in your default crafting menu.

Potential Issues

 * Damage cap Begone - Messes with damage scaling

 * Enable Monster Special Attacks - FU Already does this.
 * Non-Uniform - Works fine, but your crew will sometimes be nude

Risky, avoid

 * RealisticFURecipes - Not updated frequently enough, and is very likely not up-to-date.
 * BYOS (BuildYourOwnShip) - FU already contains a BYOS system
 * Draconis FU Addon - Outdated. Breaks things.
 * Faster Start - Frackin' BYOS requires tungsten in your starting system to repair your FTL drive. Using the mod may result in no Moons, Forests, or Deserts spawning, leading to a lack of vital resources.
 * FrackinUniverse Ground Seeders - Outdated, and FU already contains a more powerful tool to perform the same function.
 * Improved Containers - Outdated mod.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
 * Melee Aiming - Interacts poorly with FU balance
 * Named Saplings - FU makes similar changes, and NS can't handle saplings crafted in the greenhouse.
 * Tier 9/Tier 10 ships - Breaks BYOS
 * Very Varied Vehicles - Outdated, breaks vehicles.
