Update 1.60 and next steps in the evolution of X4: Foundations

Today, Egosoft is happy to announce the release of patch 1.60. You can find the full changelog for 1.60 at the end of this announcement. We would also like to take this opportunity to share our near-future plans for X4: Foundations with our community! You can find our "road map" regarding future patches below.

User review

Recently we discovered a video about X4: Foundations by Bluedrake42. We have not influenced or sponsored his video, but we are definitely pleased he’s so excited about X4 and we wanted to share his review. It’s been a great joy for the entire team at Egosoft to hear all of his comments.

“There have definitely been a few problems with bugs, and the learning curve has always been a little bit high due to the massive giant economy… but I have to say X4 is the best version of all the X Games in my opinion - the UI is way better and easier to navigate, the controls are way more streamlined.” - Bluedrake42 on YouTube

Check out his full review:

X4: Foundations Milestones

Before 2.00, and between any of the coming major patches, there will also be minor steps. We try to release bug fixes as fast as we can once we feel they are safe (which is why there will also be lots of public betas).

Update 2.00

The next bigger update will bring, among other things, the ability to set up your own shipyards. Compete with the faction shipyards by selling ships to the war factions or build your own fleets.

Another focus for 2.00 is to make crew training a bit easier. Crew and pilots gain experience by doing their jobs; more so in some areas than others. However, while the first two stars are very easy to gain, the progress slows down after that. Getting from the 3rd to the 4th star takes a LOT more experience than from the 1st to the 2nd.

We aim to release 2.00 in February.

Update 2.50
  • With 2.50 we aim to bring a new ship type: Resupply ships. In short, they will work like a flying equipment dock and can form the backbone of a large fleet.
  • Linux version: We hope the Linux beta can start somewhere between 2.00 and 2.50 already but at the latest together with this update.
  • TrackIR/Tobii support: We know lots of people are asking us to support these tools and while testing may start before it again we aim that 2.50 should bring support at the latest.
  • Sector blacklists: This will allow you to set up sectors that your ships will avoid at all costs.
  • Another thing that we hope to pack into 2.50 is a series of improvements around managing inventory items. This includes the ability to create and drop crates in space and possibly also to store them on stations.
Update 3.00
  • As some of you may already have figured out, one cool feature of X4 is the ability to own entire sectors and even change their names. With 3.00 we aim to build upon this with a number of features to help you benefit from sector control. You can then basically become your own faction with your own set of rules.
  • For all updates, we are working on better missions. At the latest for 3.00 we plan to have a number of new and improved combat missions in particular. An area we want to combine this with is improved research (in the player HQ) and the ability to potentially even move the player HQ to a different location.
  • An early gameplay feature that 3.00 will improve is the ability to dock directly at station with a spacesuit and to get other NPC ships to transport you, by offering missions to them.
  • With 3.00 at the latest, we want to have at least one new gamestart. There is a chance that this will have some interesting new features.

Online ventures

In December we released our very first online mode in an X game: Ventures. With the Updates 2.00 to 3.00 we will also continue work on more and better online ventures. So stay tuned for more exciting online missions.

You can find more detailed explanations of Online Ventures here:
X4: Foundations Manual - The Venture Feature

First Expansion will introduce Split race

While all of the above (free) updates may also contain new assets, we will bundle a lot of new ships, station modules, missions and new sectors into the first big expansion. Our rough timeline is to have an expansion based on introducing the Split race, their ships, a new Split economy and of course a large new area of space shortly after releasing 3.00.

X4: Foundations 1.50 and first X Online Mode

We are happy to announce today the availability of Update 1.50 of X4: Foundations. It adds the ability to ask people for directions, reintroduces a more talkative Betty shipboard computer and fixes a long list of issues. With this update, the game now also gets its first ever X online mode called Online Ventures.

YouTube video: Features of 1.50 and Online Ventures explained

X4: Foundations - Online Ventures
The Egosoft team today releases our first experimental online gameplay mode for any X game into BETA. We call it "Online Ventures".

With X4: Foundations online ventures, every player can send a ship into other players' universes and allow visitors into their own.

Visitors to your universe can easily be identified in HUD and on the map.

They will see your ships the way you designed and decorated them (an exception is if you created your own custom logo).

Assign ship to a venture dock before sending it into a parallel universe.

After building a VENTURE PLATFORM and a VENTURE DOCK, you can send any S or M ship on a selected venture.

Different ventures unlock different rewards. For now they are all safe!

Ventures can take anywhere from one hour to several (real-time) days and will, with a bit of luck, unlock some exclusive rewards on success.

Every player can get one venture platform and one venture dock and build it on any station or on his or her player HQ.

X4 Manual
More information about how this works can be found in our X4: Foundations Manual.

It's a BETA - More to come soon
While the online venture gameplay is now available to all with the normal version of X4: Foundations on Steam and GOG, the online feature itself is still in BETA. There is no risk to your savegames or to stability, but the ventures themselves might go wrong.

Participation in this new online mode is entirely optional and only possible with one unmodified savegame at a time!

About This Game

Freedom to personally fly all ships:

X4 will allow you to fly all ships personally. From small scouts over a wide range of ship classes up to the biggest carrier, everything can be piloted from the cockpit or an external view.

A big focus in the development of X4 has been to achieve a seamless and immersive experience when moving between ships. You can leave a ship, climb down a ladder, walk over the dock of a large space station into another ship you may have parked there and replace the pilot that was working for you just by clicking on his chair.

Modular stations and ship upgrades:

Building space stations and factories has always been a foundation of the X games. After gaining enough money through fighting or trading, most players want to establish their own economy and start influencing the universe on a larger scale. In X4, it is now possible to be completely free and creative. Stations can be constructed from a variety of modules, be it production modules, living sections, docks or many other types of parts. The powerful new map system allows you to drag and connect modules using a connection system to design your own unique creations.

Ships also offer a variety of upgrades. Engines, weapons and other equipment can be added in a graphical editor and actually seen on the ship.

Most dynamic X universe ever:

X4 will be the first X game to allow our races and factions to freely build and expand their empires; the same flexibility the player enjoys in creatively designing space stations from modular building blocks is also available to them. Races expand their empire based on supply and demand, which leads to an extremely dynamic universe where every action the player makes can influence the course of the entire universe.

Managing your empire with a powerful map:

Once you have more ships and many NPCs working for you as pilots, crew or station managers, the map will be your preferred method of managing it all. Ships can be ordered with simple clicks and through drag-and-drop operations to set their future path and commands.

Graphically plan your trade routes, coordinate attacks with your entire fleet, manage the hierarchy or send ships on remote exploration missions.

Most detailed X economy ever:

One of the key selling points of X games has always been the realistic, simulated economy. Wares produced by hundreds of stations and transported by thousands of ships are actually traded by NPCs and prices develop based on this simulated economy. This is the foundation of our living and breathing universe. Now with X4, we have taken another, massive step. For the first time in any X game, all parts of the NPC economy are manufactured from resources. Ships, weapons, upgrades, ammo and even stations. You name it. Everything comes out of the simulated economy.

Research and Teleportation:

The seamless change from ship to ship and from NPCs controlling your empire for you continues on a higher level. Once you own a larger fleet, you will be very interested in researching a technology from your HQ: Teleportation. Once you've unlocked teleportation, you can jump from ship to ship a lot quicker and experience all the critical situations your NPCs encounter first hand.

Every order you have given to a ship before turns into a mission objective when you pilot the ship yourself. The moment you leave again, your pilot takes the helm and continues with their previous orders.

Get into the game:

In X4, you can start your journey from a number of different gamestarts and as a number of different characters, each with their own role, set of relationships and different ships and technologies to start with. No matter how you start, you are always free to develop in any other direction. Focus on exploration, make money with illegal trading and theft, command large battle fleets or become the greatest entrepreneur ever. It's all up to you to decide.
