Early Access Game

Get instant access and start playing; get involved with this game as it develops.

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?

“No, the price now is the final price.”

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 #303 - Under 100 bugs (but still not stable)

Read this post on our website.

Under 100 bugs
We have a record low in our bug report forum, of only 55 active bug reports. I don't think in the history of Factorio the bug forum has been so clean. No doubt once we mark 0.17 as stable the count will shoot up again.

For this weeks graph I added the count of players on Steam as the left axis. We thought it would be somewhat interesting to see if there is any correlation between the two.

Note: The axis have different scales.

I also prepared the same graph but for the duration of the 0.17 release. You can see our player numbers are dropping quite a lot, from the all time peak of 22,457 on the 3rd of March 2019.

While bug reports might be at an all time low, we are not going to call the game stable yet. We still have an important milestone to reach, that is, implementing the new Introduction campaign graphics (FFF-301). A lot of the team has been on vacation these last few weeks, including the whole campaign team and most of the art department. What this means is that we expect it will be a few more weeks before we can call the current version stable.

We have been asked a few times when stable will be released, but my question is, why does it matter exactly which version we call stable? Are you waiting for stable to play a new playthrough? The thing is, this stable is only going to be the 'first' stable. Our plan is to have a number of short experimental phases after the first stable, where we will add new GUI's and such, which will add bugs and technical debt. After fixing the bugs in a 'small' experimental content release, we will then mark that as the 'new' 0.17 stable.

Besides, there are still a few edge cases with signals that kovarex is busy fixing:

For instance the setup above took him 3 hours to fix. The cause of the issue was that the segment has both an incoming and outgoing signal at the same position.

G2A - Worse than Piracy
There was recently some news about G2A, prompted by a tweet by Mike Rose of No More Robots. In a follow up tweet he said: Please, if you’re going to buy a game from G2A, just pirate it instead! Genuinely!.

We have talked about the grey market resellers in some previous Friday Facts (FFF-145 and FFF-171), and our stance is pretty much the same as Mike, we would rather you pirate Factorio.

Upon hearing the news of G2A advertising Descenders, we took a look ourselves, and we discovered they were doing the same with Factorio:

Obviously we aren't super happy about it, but after looking into some trademark/copyright law, it seems there is not much we can do.

After the news broke, G2A posted an article on their website: {LINK REMOVED}. After reading it through, I thought I would take them up on their offer.

We had a ton of chargeback and fraud issues in 2016 just after our Steam launch, with over 300 Steam keys of the game being purchased with stolen credit cards. With an average chargeback fee of about $20, we estimate the total amount of fees we paid because of chargebacks is about $6,600. We will be doing a deeper evaluation of our historic accounting records to get a more exact figure, but it doesn't matter so much now.

So I emailed G2A about the article and their 'vow' last week, and they are not exactly prompt in terms of dealing with the request. I have a list of all the Steam keys I had to revoke because they were purchased fraudulently, and G2A offered to check the keys. Currently this is where the story ends, they haven't replied to my last email (2 days ago) sending them the keys and asking how many of them were sold on the website.

Funnily, we already know that at least some of the keys were sold on G2A, because after I revoked them, I had people emailing to ask what was wrong with their key:
  • Hello, on 2016-12-26 I bought my brother a Factorio steam cd key from G2A website. On 2017-01-20 he got a message on steam that the game was revoked. What happened and how can we solve this issue?
  • Hey, I got this game from my friend on my birthday a while back, March 11thish. He sent me it by key, I didn’t really question it. Yesterday, though, I was greeted by a popup telling me the game had been removed. After investigating, I learned my friend bought it from a site called G2A, little shady site from what I hear. Steam support says it was “revoked at the request of the publisher.”
  • I bought Factorio on G2A last week for Steam. However, I can't find it in my Steam library anymore.
  • On 3 March I bought the game Factorio on G2a It was 5 euro cheaper than on your website so I thought let's buy it here. But today I got a pop-up from steam saying that my Factorio steamkey has been revoked because of a problem with processing payment for this item.
  • Today i logged in, after playing this game rougly 300 hours and about 2 month and got a message that Factorio was removed from my account. I got my key from G2A.
  • I bought Factorio on steam a while back and when i went to play it, it said i had to purchase it. I contacted steam and they said that it had been revoked and i should contact the publisher. How and will i get the game back? I bought the game off of G2A.
  • I bought the game on g2a and got the steam product code and my account is saying that I don't have the game bought.
Well anyway, after we switched payment providers to Humble Widget, the fraudulent purchases stopped. We don't really care about G2A anymore (but we are in a unique position due to our no sales policy).

There are still Steam gifts of Factorio being sold on G2A, these are most likely 'legit', in that they were not purchased using stolen credit cards. The question is, where do these gifts come from? Obviously people would not be selling Factorio Steam gifts if it did not generate a profit. We have some ideas:
  • Regional fraud - Buying the game in 1 country and gifting it to someone in another. This is likely, as we can see that the Europe gift is cheaper than the US/Worldwide.

  • Speculative buyers from before the price increase - The price of the game was $20 a year ago. So buying 1,000 copies and waiting 1 year, nets you a profit of $5,000 if you sell for $25. Not a bad gain in a year. For Factorio the opportunity only came once, but other games go on sale multiple times each year, which is where the speculative buyers and the grey market cash-in.
To conclude this whole topic, we strongly recommend people buy from us or one of our official partners. Not only for the reasons you might think. If you buy from a grey-market site and have a problem with the game, or something goes wrong, you will have to deal with their support system. I don't have the exact details of how to request a refund or customer support from G2A, or how long they will take to respond to your issue.

If you buy from us directly, we offer a 28-day refund policy. If you have a problem with the game, you decide it's not your cup of tea, you thought the biters were too cute, just send us an email and you will have a refund in short order. We also deal only with Factorio related support problems, we don't process orders of thousands of different games, so you can be sure your case will be handled expediently by team members who know the game in and out.

As always, let us know what you think 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.
