📋 About This Mod

!! IMPORTANT FOR 9. 00 UPDATE !!!

=====================================

If you continue an existing game, you should update the mod right before you load your savegame into 9. 00, otherwise the weapons of the ship will be misplaced. If you continue a Beta-Game or missed that, you need to edit the savegame you want to load and change the version in line 5 to "800". With this, you trigger a mechanism in the game to relocate components which normally cant be relocated.

=====================================

The Tsurugi is an S class heavy fighter for the Terran Protectorate.

It is basically an upgraded version of the Kukri.

It can be bought at Terran wharfs. The player can also buy the blueprints for the ship and build it on own wharfs.

The Tsurugi is considered a super heavy fighter as it has 4 shield and 4 weapon hardpoints but in return it has the worst speed and maneuverability of all terran fighters.

Important Update 2. 0 Information:

Because of major changes in X4 6. 0, new collision meshes had to be created. They will be used for every ship - also already existing ones.

They also changed some stuff regarding the components like engines, shields, turrets,...

Existing ships should still work but i expect you will be unable to change equipment on them. New ships will not be affected by this.

Equipment:

1 S-Engines

4 S-Shields

4 S-Weapon Hardpoints

Languages:

other languages will be added if someone is so kind and translates :-)

AI-Usage and Balancing:

Some of the terran shipgroups, which include a collection of useable ships, have been extended by the new fighter with a weighted value.

You will see the ship here and there, from time to time.

If you continue an existing game, it will take some time as the ship comes slowly into service.

On a new game, you will see it more commonly.

Prerequisites:

X4: Foundations

X4: Cradle of Humanity

The ship was developed and tested with versions 5. 00 and 5. 10

Installing:

You just extract the archive into your extensions folder.

It should then look like that: ..\X4 Foundations\extensions\lc4hunter_terran_tsurugi

Known Issues:

The ships ID-Code does not work.

Because of that, the ID-Code was removed (will be added again when it works).

Special Thanks:

I would like to thank the whole X4-Modding community on the forums and the Discord for their support!

Thanks to X - Save Scum for his help regarding the shipgroups.

📊 Pros & Cons

✅ Pros

  • Solid community backing with 388 endorsements and nearly 20k downloads.
  • Adds a meaningful new ship with a distinct trade-off: heavy firepower but sluggish handling.
  • Integrates with AI shipgroups, so you'll see it in action, not just in your own hangar.

⚠️ Cons

  • Updating to game version 9.00 requires precise timing or save editing to avoid weapon misplacement.
  • Existing ships from before the 6.0 update may have issues changing equipment.
  • Compatibility risk with other mods that alter Terran ship lists or components.
🎯 Is This For You?
For X4 players who want a new Terran fighter with a heavy-hitting loadout and don't mind sacrificing speed. It's perfect for those who enjoy flying tanky ships and building their own fleets. Skip if you prefer fast, agile fighters or if you're not comfortable with save editing during major game updates.

💡 Beginner Tips

  • If you're updating from an older version to X4 9.00, update the mod right before loading your save, or edit the save's version line to '800' to fix weapon placement.
  • When buying the Tsurugi, check its stats compared to other Terran fighters—it's a tank, not a speedster.
  • If you want to see the ship in AI hands, be patient: it takes time for new ships to appear in existing games.
