What the developers have to say:

Why Early Access?

“We have been working on Factorio for over 5 years. The game is very stable and is highly optimised for prolonged gameplay and creating huge factories. We have sold over 110,000 copies on our website, and we feel now is the right time to release to a wider audience.”

Approximately how long will this game be in Early Access?

“Our plans for release come as part of an ongoing process, and we are constantly adding new features and content. When we feel the game is complete we will release the full version, and our current estimate is that this will take 8-12 months.”

How is the full version planned to differ from the Early Access version?

“In the full version we hope to have a polished GUI, a multiplayer matching server, integration of mods for players and servers, and a number of other finishing touches and additions to the core gameplay.”

What is the current state of the Early Access version?

“The game has a very strong content base, rich with interesting mechanics and features. Many players report they are still having fun on their maps even after hundreds of hours of gameplay, alongside multiplayer support, and a dedicated modding community.”

Will the game be priced differently during and after Early Access?

“The price may be increased upon release from early access.”

How are you planning on involving the Community in your development process?

“The community is a vital part of our development process. We announce any planned features far in advance so we have time to read peoples' opinions and comments, and for us to discuss the different points of view players may have. Community suggested ideas are commonly brought up in team discussions, and we value highly the input each individual player can have.”

Friday Facts #239 - PAX East report

AMD Ryzen crashes
The long fight with the elusive Ryzen bug (more and more) seems to finally have some resolution.

A few weeks ago I sent an email to AMD, filling them in on the details of the crash, and asked them if they could help us solve this. Very quickly I was put in touch with a member of their CPU engineering team, and they got to work with their investigation. After a few days, and after providing them all the information we have (log files, source code, crash dumps etc.), the cause of the issue was identified.

Some other developers in the industry also had this problem and worked with AMD to fix it, so it's unlikely that the CPU bug was fixed only because of us, but we are honoured to have contributed to this. Unfortunately we do not have any technical or deep insight into where exactly the problem lay, or what the fix was, as it was somewhere between the motherboard BIOS and the Ryzen chipset drivers.

So if you are running Factorio on a Ryzen system, we advise you to update your BIOS using the files and procedures found on your motherboard manufacturer's website, and update your chipset drivers to the latest version.

PAX East Report
Two weeks ago we travelled to Boston to showcase our game at PAX East. I really like games and game conventions, so I was the lucky one who got to go to PAX East, after having already attended the Taipei Game Show. I was joined by Rseding91, v453000, Klonan, HanziQ and Jiri.

Compared to Taipei, PAX was much larger, with a lot more players reacting positively to Factorio, and many more people knowing the game.

We had a 4 banners showing the base mentioned in FFF-236, a TV playing the trailers, and PCs with the first two levels of the campaign (the first one was shortened quite a bit). These worked well together. The trailer got people hooked, the demo showed them what the game is about and the banners showed them that the game is very deep and complex.

We noticed a few categories of people coming to our booth (in order of most frequent):
  • Fans who already knew the game and wanted to show their appreciation, thank us or get some merchandise (we really should have brought more pins and t-shirts). Many of them would say "I wasted hundreds of hours in this game, you guys almost ruined my life".
  • Groups of friends passing by our booth, with one of them telling his friends "Oh, Factorio! Man, this game is amazing you guys really need to play it!". They would then proceed to explain the game to their friends.
  • People who heard about the game and wanted to give it a try.
  • People watching the trailers and having a chuckle when the biters get hit by the train.
  • Every one else who sat down to play the demo, either stopping after the first short level or playing all the way to the end of the second, longer level.

Like last time, it seems that the event didn't bring us much sales, but it's hard to judge since we already had a spike in sales when we announced the price increase and 0.16 stable. Nonetheless it was definitely nice to be there and meet the fans, other developers and members of the industry, and to play all kinds of games that were being demoed. It was also a great learning experience for us, in both event management and the impression that the game leaves.

Special thanks to RaZer and Dell Alienware for lending us the PCs for demoing the game.

While there I filmed some short clips, including a few with our booth and edited them into a video. The quality is pretty bad since I accidentally set the camera to record in 640x480. You can see the video on my personal Youtube channel here.
We also made a small album with some photos here.

After PAX, HanziQ and Jiri visited New York City, while Rseding91 and I went to Los Angeles where we visited the Blizzard campus, Six Flags and also had a small meetup with a few Factorio fans.

As always, let us know the way you feel on our forum.

About This Game

Factorio is a game in which you build and maintain factories. You will be mining resources, researching technologies, building infrastructure, automating production and fighting enemies. In the beginning you will find yourself chopping trees, mining ores and crafting mechanical arms and transport belts by hand, but in short time you can become an industrial powerhouse, with huge solar fields, oil refining and cracking, manufacture and deployment of construction and logistic robots, all for your resource needs. However this heavy exploitation of the planet's resources does not sit nicely with the locals, so you will have to be prepared to defend yourself and your machine empire.

Join forces with other players in cooperative Multiplayer, create huge factories, collaborate and delegate tasks between you and your friends. Add mods to increase your enjoyment, from small tweak and helper mods to complete game overhauls, Factorio's ground-up Modding support has allowed content creators from around the world to design interesting and innovative features. While the core gameplay is in the form of the freeplay scenario, there are a range of interesting challenges in the form of Scenarios. If you don't find any maps or scenarios you enjoy, you can create your own with the in-game Map Editor, place down entities, enemies, and terrain in any way you like, and even add your own custom script to make for interesting gameplay.

Discount Disclaimer: We don't have any plans to take part in a sale or to reduce the price for the foreseeable future.
