Early Access Game

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

Note: This Early Access game is not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

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 will not increase after 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 #248 - Not Saturday Facts

Status report
On Monday June 18th, we marked the last version of 0.16 as stable. There were no major problems, so now we are almost exclusively working on 0.17. Work on 0.17 is progressing well:
  • Regarding the new campaign, we are already internally playing a rough version of the new player experience.
  • We are still trying to figure out the exact and final style and concepts for the improved GUI, but we have some GUI windows implemented in game already, plus many base widgets. We use those to get a feel of what works and what doesn't.
  • The new graphics back-end rewrite is nearing finalization. A closed-beta branch was sent to a few players to test that rendering works correctly across different hardware. The rendering is faster and no major issues were reported so far. But there is still much to do, such as improvements to VRAM usage and many experiments with shaders.
  • Since from the graphics department Albert is working on the GUI and V453000 is working on the new campaign, only Ernestas is left working exclusively on the entity graphics. He is reworking some more entities for high-resolution, so expect some teasers in the future.
  • There are of course other small projects that are ongoing, such as improved pipe-fluid physics and improved map generation, but more on those when they are fleshed out.
Oh, and our coding always goes as planned without any problems.

Modding support
With every major version of Factorio, we work on improving the Lua API and modding support. In 0.17 I've been looking at cleaning up my back-log of things that I've wanted to implement for quite some time but never got around to. Things such as:
  • Sync mods with a server you want to join.
  • Having multiple versions of a mod installed and being able to switch between them.
  • Letting mods set entities to not require power.
  • Adding support to clone entities/areas of the map from one location to another.
And in general looking at "hacks" that mods are currently doing and seeing if it's reasonable to make the game support what the mod was trying to do in a non-hacky way. Bilka and I have been going over the Mod Interface Requests section of the forums and cleaning it up; implementing things that make sense and taking care of outdated or won't-implement requests. Time and time again Bilka will ask "why can't I do X with a mod?" and the answer is almost always "because nobody asked for it so nobody added support for it". So with that said: if you're a mod developer and think the mod API is lacking something feel free to stop by the forums and ask for it.

Fan Mail
A few weeks ago Demod was showing us some 3D printed belt keychains he made, and mentioned he wanted to send some to us. I showed it in our team slack channel and many us wanted them. A lot of 3D printing later, he sent us a nice package with gifts for most of us.

Hate Mail
You can't receive fan mail without receiving some hate mail. We also received an anonymous package telling us to "eat a bag of d*cks", along with a bag of tasty gummy d*cks. The truth is I know who sent it and it was just a small practical joke. They were trying to show their frustration with the matching server in a friendly-funny way. We thoroughly enjoyed shoving them down our throat.

As always, let us know what you think on our forum.

Friday Facts #247 - Pricing and its exploits

Regional pricing exploit
Earlier this week I received an unusual number of support emails, some players were having trouble redeeming their Steam keys on our website. In each case, the key they purchased was not a key eligible for a Steam key. Our order/account system isn't the most intuitive, so let me explain the ways in which people can buy the game, and how it relates to our website:
  • Our website - You buy from our website, and you get a key from the Humble checkout. You use this key to upgrade an account, and you can redeem a Steam key.
  • Steam - You buy on Steam, which adds it to your Steam account. You then link your Steam on our website, which upgrades your account.
  • Humble Store - You buy a Steam key, which you activate on Steam, and then follow the steps above.
  • GOG - You buy the game on GOG, which lets you download the DRM free version. You can also redeem a retail key, to upgrade your account.
So in the cases above, the only way to get a Steam key from our website, is by buying directly on our website. The players in question managed to get their hands on 3rd party retail keys. These retail keys aren't distributed for reselling anywhere, so the fact I was seeing a lot of emails coming in about these keys, was an indication something fishy was going on.

The source of these keys is GOG, I double checked this my comparing some of the keys these people purchased with the list of keys we generated for GOG, and they matched. My first suspicion was someone cheesing the GOG return policy, buying the game, redeeming the key, and then refunding it. I emailed our contact and there were only 21 refunds in the last 3 months, so it was not the case.

The second suspicion was that the GOG server was breached somehow. They reported no incident, but we disabled all the unredeemed keys anyway just to be sure. I checked with the list again, and none of the keys that we deactivated were used by any account. This led to the conclusion, at the very least, these keys were purchased legitimately.

So people are legitimately buying keys, GOG confirmed sales had shot up in the last week. Then the question, where are the sales coming from? One last email to GOG and we had our answer: Russian Federation. The reason? We have regional pricing on GOG at parity with Steam, which means someone buying from Russia could buy the game for ~$8.30. Once they buy on GOG, they can redeem the retail key, and sell it for about $20 on a 3rd party site. So one clever guy saw this opportunity, and started buying the game hundreds of times on GOG. The immediate solution is to remove the regional pricing, and in the long term we may be able to implement some 'GOG linking' similar to the current system for Steam users.

It is strange that it was only taken advantage of recently, as we have had regional pricing since our launch on GOG 2 years ago. It may be related to the recent price increase.

Price change reception
At the end of March, around when 0.16 was first made stable, we announced the price change from $20 -> $30. I thought it would be interesting to see what affect it had on sales, and as showing it better than telling, here is a graph of units sold between February and June:

It is quite clear there is a huge spike when we announced the change, and again just before we implemented it, but more interesting is the comparison from before and after. You can see that there is a noticeable decrease in sales before and after, but overall it is still quite strong and consistent. This reflects most of the player reaction to the announcement too, many people were commenting that they support the price increase, and believe the game is still worth the asking price (if not more).

Regardless of the recent changes, we have had consistent week-on-week sales of the game since our Steam launch, and we are fast approaching 1,500,000 copies sold. I think in part, this is due to our no sales policy, but that is a discussion for another day.

Satisfactory game
We were all excited early this week, when we saw the reveal of another title in the automation and simulation genre:


From the point of a player I would say that the trailer looks amazing. The energy of it, the looks, the potential, the promise is fantastic. I don't doubt that our office will be playing from the day 0 once it is released. Let me quote /u/european_impostor by saying: "They've certainly talked the talk, now let's see if they can walk the walk".

From the point of a Factorio developer, I would say that it makes me proud and insecure at the same time. As the game is undoubtedly inspired by Factorio, it makes me proud that we most probably helped to make this "genre" become a thing. It makes me insecure as well, as it could also completely overshadow our game. To that, I would say, that if they managed to do a game that is better then Factorio on every level, then they deserve it. If there are still going to be areas where Factorio is better, the potential success of the game can actually help us, as when more people come to play the game, more people will eventually look for alternatives in the similar way as the people asking for "other games like Factorio" from time to time.

If there is some takeaway for us, then it is, that we shouldn't wait with finishing the game too much. 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.
