📋 About This Mod

IMPORTANT NOTE: You need to remove the old mod before using this one, otherwise you will have bugs and errors.

The Xenon (Fleet) Overhaul was made to add some more variety to the Xenon faction with some new (and old ;-) ) ships, weapons and some adjusted jobs to make them be used by the AI.

I tested the mod myself for several weeks now and it does what it should.

It improves the Xenon as a threat. In some cases, Xenon can slowly wipe out sectors and expand. The factions will not be able to hold them off except the player helps. This is intended. Please keep this always in mind before using this mod.

The mod can be added at any time of the game (except you already whiped out the Xenon...).

What will be added:

Ships:

- Xenon G (which was made by SirFrancisDrake and has been slighty modified by me, thanks a lot my friend!)

a new and powerful battleship for the Xenon. It has slightly improved values then the K and is a bit more balanced in regard of its turrets layout.

- Xenon Q

a rebuild of a Xenon ship feared by players in X3. It is very poweful for its size and usually never comes alone.

- Xenon Fighter rework

replaced the existing fighters with their X3-versions.

Weapons:

- Q-mainbattery

The mainbattery for the Q. Basically an L-variant of the known Xenon mainweapon.

- Graviton beam turret

A new turret based beam weapon for the Xenon with a good range and damage.

- Xenon flak turret

Similar to the Flak cannons of other factions, this long range weapons is a decent anti fighter and anti surface structure weapon.

Variants:

As Xenon capital ships have loadouts predefined, i had to create variants of the K and I to make them use the new beam turret.

Languages:

English

AI/Jobs and Balancing:

I mostly modified existing jobs/ship lists to make them use the new ships.

For example i modifed the ship-selection list for the "Xenon destroyer" jobs to make them use the G. This means the AI builds a new Xenon Capital ship and there is a percentage based change that is builds a G instead of a K. The overall amount of Xenon capital ships remains untouched.

For the Q i had to create some new jobs.

I changend nothing to the AI. No scripts where added to this mod.

I know there are some mods out that change AI-behavior of the Xenon. I cant tell if those modes are compatible with my mod, but from what was made here, i think it should be.

The ships were build and balanced around Vanilla. I had no other mods in scope when making those.

Prerequisites:

⚠️ Cons

  • Requires removing the old mod before installing this one, or you'll get bugs and errors.
  • The Xenon can become too powerful, potentially overwhelming factions unless the player intervenes.
  • Compatibility risk with other mods that alter Xenon ships or AI jobs, as this mod heavily modifies them.
🎯 Is This For You?
