X4: Foundations – How to Easily Reach the Combat Rank X-TREME

A comprehensive guide on how to reach the Combat Rank X-TREME in X4: Foundations. Learn the strategy behind 60,000 kills and the 0.1% Steam achievement.

This walkthrough provides a relatively simple method to achieve the highest combat rank Steam achievement X-Treme Fighter and unlock this rare Steam achievement.


The combat rank X-TREME is primarily achieved by scoring killsgame statistics. Hostile capital ships are a rare sight, but they yield significantly more combat points than smaller fighters. Destroying enemy stations also awards points, though this approach should be handled with caution and care.

Combat Rank Point Values
Points Activity
1 Destroyed S/M ships (fighters, corvettes, etc.)
1 Destroyed turrets
3 Completed missions
10 Taken over unclaimed ships
10 Destroyed station modules
30 Destroyed L & XL class ships (destroyers, carriers)


Some players construct a powerful fleet and launch massive invasions into Xenon sectors, showing no mercy even toward their space stations. While this aggressive approach is far from trivial and noticeably increases your combat rank, it will ultimately not lead to X-TREME. Eliminating the Xenon entirely might represent a satisfying personal milestone for certain pilots, but it is simply not the correct path to achieving the highest combat rank.

To amass the required 100,000 points, there are simply not enough enemy ships available in the entire X-Universe. Therefore, you must allow your opponents, preferably the Xenon, to continuously rebuild their destroyed vessels. While you can simultaneously go hunting for pirates, they usually disguise themselves as other factions, and attacking them will severely damage your reputation with those respective races. You would have to scan and scan again to unmask the pirates first before safely destroying them — which is an incredibly tedious process. A faster alternative is to instigate a war between the major factions and actively participate in the battles. However, this high-stakes strategy creates an additional enemy that will inevitably target your own traders and stations.

The only reliable enemies are the Kha'ak and the Xenon — fighting them is completely free of collateral damage. Marauding Kha'ak are rare, and you will only encounter them in larger numbers if you assault their stations, which are equally hard to find.

Alternatively, you could initiate the Sensor Analytics research Fleet-wide Sensor Analytics research project with Boso Ta, which subsequently spawns a massive wave of enemies. Mastering this Xenon Crisis is a monumental challenge, as your own installations and fleets will be under constant attack universe-wide. Alongside countless fighters, you will face numerous Xenon and Kha'ak capital ships. It is a grueling ordeal that drives many players to abort the disaster by reloading an older save game. However, the sheer volume of kills achievable during this period significantly boosts your combat rank. But beware: only ships you destroy personally contribute to your combat rank. Deploying your own fleet to eliminate capital ships will not increase your rank. You must be at the helm yourself, making this entire adventure Steam achievement Crisis Averted highly difficult.

After a few intensive days of combat, once all enemy attack waves have been successfully repelled, you will have to set out and hunt for opponents once again.

I constructed a powerful AsgardAsgard technical specifications and heavily upgraded its shields. With this ship, I repeatedly visited the Yaki station in Savage SpurPath to the Yaki Station. On the way there — navigating through Tharka's Cascade XV, XVII, Matrix #79B, and into Savage Spur I — you are greeted by countless Xenon ships. However, their attacks were highly welcome. My combat rank increased steadily, and the active Container Magnet delivered valuable modification parts and spacefly eggs. During these runs, I always flew close to their stations to lure out the defense ships, without destroying the stations themselves. Throughout the slow flight, and even in the heat of battle, I managed my own stations, traders, diplomacy Spymaster achievement and terraforming Terraforming - impossible difficulty projects from afar. The Asgard's turrets did all the heavy lifting. The best setup here proved to be L-Beam Turrets (because they never miss) and M-Shard Turrets. The extremely powerful main battery was only deployed against enemy capital ships.

However, you should always keep a close eye on your surroundings (so don't just run out to the local grocery store while the Asgard is moving). There were situations where I encountered major Xenon battle groups. When an I suddenly appears along with five Ks, Hs, and 50 fighters, even an upgraded Asgard requires caution. The Ks like to position themselves directly above their targets, making it a slow process to aim at them with a bulky Asgard. Meanwhile, other Ks and Hs can close the distance enough to inflict serious damage on your ship. The I is very sluggish; you should simply keep an eye on it, maintain your distance, and deal with it as the final capital ship.

The weak point of the Asgard is its main engine. If it fails, leaving the Asgard immobilized while enemy capital ships are closing in, it is game over. Therefore, remember to save your game regularly. You can monitor the engine damage and, if things start to look critical, throw the ship into reverse. This significantly reduces the number of fighters targeting your engines, allowing the damage to be slowly repaired. Carrying repair drones and a large service crew on board should go without saying.

Eventually, I decided to free Heart for Pirates achievement the Yaki from their plague and conquered the surrounding Xenon sectors. It turned out I had discovered an even easier method to work on my combat rank.

Asgard in Position
I drove all Xenon out of Family Nhuut and built defense stationsdefense stations at the north and west gates to stop all incoming enemies. Behind the western gate of Family Nhuut, in Family Zhin, I took up a positionposition in Family Zhin myself, interceptingholding position at eastern gate of Family Zhin all arriving Xenon ships at the eastern gate of Family Zhin. Apparently, they desperately wanted to reclaim the resource-rich territory of Family Nhuut and relentlessly dispatched groups of ships in that direction. Here too, things sometimes got hairy when multiple capital ships appeared at once or the Asgard became overwhelmed by the massive flood of fighters. A defense station built near the gate provided huge relief; the Asgard could slowly circle it until the critical mass of enemy fighters was neutralized.

While the Asgard drifted in space, autonomously performing its gate-guard duty, I had plenty of time to expand my trading empire, pursue terraforming Ocean of Fantasy terraforming achievement, and engage in diplomacydiplomatic relations I only handed the controls over to my copilot when I had to accept a new rank somewhere or needed to scour a few stations for Rare Spices — the Xenon provided more than enough eggs required for Spacefly Caviar.

This approach to reaching X-TREME was highly efficient and entertaining — there was always something to do while the Asgard independently held off tens of thousands of enemies.

However, after achieving the highest combat rank, completing several terraforming missions, and with three personal shipyards earning billions, the game suddenly offered no challenges left for me. I decided to start fresh with a different plot. Now, it's time to tackle the highest trade rank.
