Egosoft released X4 on 30 November 2018 as the first X game where you can fly every ship, walk around stations and build stations of your own module by module. Ships come in four sizes, with S and M built and sold at Wharves while L and XL come from Shipyards, which decides where a damaged fleet can actually be repaired. Expansions have widened the map considerably since launch, adding the Split, the Terrans, the pirate space around Avarice and the Boron kingdom.
Starting X4: Foundations can feel overwhelming. This guide tells you exactly what to focus on during your first hours so you don't waste time on things that don't matter yet. For the full progression path, see our walkthrough.
What Kind of Game Is This?
X4: Foundations is a simulation game built around Four ship size classes from S to XL and Station building with modules and plots. The core loop involves mastering these systems to progress through increasingly challenging content.
What to expect: Time investment in learning mechanics, experimentation, and gradual mastery. The game rewards patience and knowledge.
Choosing Your First Build
| Build | Beginner Rating | Why |
|---|---|---|
| S class scouts and fighters | Excellent for beginners | Balanced approach |
| M class corvettes and frigates | Excellent for beginners | Balanced approach |
| M class miners and traders | Excellent for beginners | Balanced approach |
| L class destroyers and freighters | Excellent for beginners | Balanced approach |
| XL class carriers and auxiliaries | Excellent for beginners | Balanced approach |
Our recommendation: Start with M class corvettes and frigates. It offers the most forgiving experience while teaching core mechanics.
Avoid XL class carriers and auxiliaries as your first pick. It requires deep knowledge of game systems to use effectively. Once you're ready, check our classes guide for all options.
First Session Step-by-Step
Step 1: Learn Four ship size classes from S to XL
S and M ships are built, equipped and sold at Wharves, while L and XL ships come only from Shipyards. That split decides your logistics, because a destroyer that loses its shields several jumps from the nearest Shipyard is a very long, very slow flight home.
This is the foundation. Spend your first 15-30 minutes getting comfortable with how Four ship size classes from S to XL works before worrying about anything else. Our combat guide breaks this down further.
Step 2: Head to Argon Prime
The Argon Federation core sector and the usual first stop for new players. It holds shipyard and wharf facilities, plenty of trade traffic and faction representatives who will buy the sector data you gather on your first exploration loop.
Clear the main content here before moving on. Everything teaches fundamentals you'll need later. See our maps guide for all locations.
Step 3: Get Your First Upgrade
Look for Beam Emitter: it's the most accessible early upgrade. A continuous beam with perfect tracking, which makes it the answer to fast targets that ordinary projectiles cannot lead. Damage per second is modest, so it is a support weapon rather than a main gun.
Step 4: Understand Station building with modules and plots
You buy a plot in a sector, lay out production, storage, docking, habitation and defence modules, then feed a Construction Vessel the materials. Habitation modules staffed with the matching species raise workforce, and workforce pushes production output well above the base rate for free.
This is the system most new players overlook. Invest time here early. It pays off throughout the entire game.
Step 5: Push to Grand Exchange
The Teladi commercial hub, thick with trade stations and the widest variety of wares in one place. Prices here are usually the reference point you compare every other sector against when planning routes.

Four ship size classes from S to XL

Station building with modules and plots
You buy a plot in a sector, lay out production, storage, docking, habitation and defence modules, then feed a Construction Vessel the materials. Habitation modules staffed with the matching species raise workforce, and workforce pushes production output well above the base rate for free.
Crew skill and pilot stars
Pilots, managers and marines all carry a star rating, and a low star pilot flies badly, trades badly and dies quickly. Seminars bought from faction representatives raise skill instantly, which is far faster than waiting for a two star trader to grind their way up through completed runs.
Trade and mining automation
Once a ship carries the right software and a pilot with enough stars, you can hand it an autotrade or automine order plus a range of sectors and it will find its own routes. Traders assigned to a station manager are more reliable than free traders because they buy against your own station's actual shortages.
Faction reputation gating
Every faction tracks reputation with you separately, and reputation gates blueprints, equipment licences and the maximum ship size you are allowed to buy. Killing Xenon inside someone else's territory raises it quickly, which is why police and escort work for one faction beats scattering effort across five.
Common Beginner Mistakes
1. Buying a large ship before buying pilot seminars, then watching an unskilled captain fly it into a Xenon patrol
2. Building a station without habitation modules and wondering why production sits far below the numbers shown in the planner
3. Grinding missions for five factions at once, which leaves reputation too low with all of them to unlock any worthwhile blueprint or licence
4. Sending a destroyer to attack a station alone, since station turrets out range most main batteries and there is nothing to draw their fire
5. Fitting a mining ship with a Mining Drill and then sending it to collect gas, which it physically cannot do
First 5 Hours Checklist
- Understand Four ship size classes from S to XL and Station building with modules and plots
- Choose M class corvettes and frigates as starting build
- Clear Argon Prime main content
- Acquire Beam Emitter or equivalent upgrade
- Reach Grand Exchange
- Buy seminars from faction representatives before you buy your second ship. A one star pilot cannot be given autotrade orders at all and a two star pilot picks poor routes, so 30,000 credits of seminars converts a useless hull into an earning one immediately.
- Drop Advanced Satellites over every trade station you visit. They feed live prices back to your map permanently, and without that coverage the trade filter can only show you data you have personally flown past, which makes route planning guesswork.
Tips for New Players
- Buy seminars from faction representatives before you buy your second ship. A one star pilot cannot be given autotrade orders at all and a two star pilot picks poor routes, so 30,000 credits of seminars converts a useless hull into an earning one immediately.
- Drop Advanced Satellites over every trade station you visit. They feed live prices back to your map permanently, and without that coverage the trade filter can only show you data you have personally flown past, which makes route planning guesswork.
- Scan station signal leaks whenever you dock. Repairing a leak can pay out credits, illegal ware information or a free module blueprint, and blueprints bought from a faction cost hundreds of thousands of credits each.
- Add habitation modules to every station you build, matched to the species that will staff it. Workforce raises production output substantially above the base rate, so a station without habitation is running at a permanent discount to itself.
- Never send an L class ship anywhere alone. Large hulls turn slowly and their turrets cannot cover every angle, so a handful of S class attackers will strip a lone destroyer over several minutes while it fails to bring a single main gun to bear.
- Pick one faction to build reputation with first rather than doing missions for everyone. Reputation gates blueprints, equipment licences and the size of ship a faction will sell you, and spreading effort across five factions leaves you locked out of all of them.
- Assign traders to a station manager instead of running free autotrade wherever possible. Station traders buy against your own facility's real shortages and sell your real surplus, which is more predictable than free traders chasing whatever spread they happen to find.
- Match the mining hardware to the resource. Ore, silicon and ice need a Mining Drill and a collector, while methane, hydrogen and helium need a Gas Collector. A ship fitted for the wrong one will sit at an asteroid field doing nothing.
- Keep an auxiliary resupply ship behind any combat fleet. It rearms fighters, replaces missiles and repairs hulls in the field, which is the difference between a fleet that can fight three engagements and one that has to fly back to a Shipyard after every fight.
- Use travel drive between gates, but drop out of it before entering a contested sector. Travel drive collapses your shields to nothing on activation and takes time to spin down, so arriving at a Xenon gate at travel speed usually means arriving without protection.
Frequently Asked Questions
Is X4: Foundations multiplayer?
No. X4 is single player only. Everything else in the universe is simulated by the game, and the economy keeps running whether you are watching it or not, which is why a station you built two hours ago can be out of stock when you return.
Which game start should a new player pick?
One of the base game starts that gives you a small S class ship and a modest amount of credits. It teaches flying, trading and scanning before you have anything expensive to lose. The Terran Cadet start is a different technology tree with poor Commonwealth reputation, so it is a second campaign rather than a first.
Do I need the expansions?
No, the base game is complete on its own. The expansions add the Split, the Terrans and Sol, the pirate space around Avarice and the Boron kingdom, along with new hulls and weapon families. They widen the map rather than change the core systems.
Where do I repair a large ship?
At a Shipyard. S and M ships are built, equipped and repaired at Wharves, while L and XL ships need a Shipyard, so plan your fleet's operating area around where the nearest friendly Shipyard sits.
How long before I can afford my own station?
Usually 15 to 30 hours for a first small production module, depending on whether you trade manually or automate early. Scanning signal leaks for free blueprints cuts that considerably, since buying module blueprints from a faction runs into hundreds of thousands of credits.
