Hello, another year has come and gone.

We know this year we were very sparse with any details about the expansion, and it is what you all really want to hear about. Trust me we really want to tell you about it, and in time we will. There are still major sections of the gameplay being changed and adjusted, and if we tell you about them now, the information would quickly become outdated and inaccurate.

For now, we can offer this Christmas postcard Albert has made, which has a sneak peek of some new item icons.

As well, we do have some other topics we can discuss, on our website.

We have a long history of trying to bring Factorio to other platforms, including consoles and mobile phones (not including April Fools). We even worked with some external companies, but the projects never even got to the point where they would run technically, let alone the complicated part of making the game playable using controllers or touch screen. After all the attempts, we even had a Friday Facts prepared that was going to say something along the lines of "we don't plan to bring Factorio to other platforms".

However that turns out to not be the case, and we also have an update about the progress on the expansion. Read the full blog post on our website.

No doubt you have heard about NFTs, the latest Blockchain innovation. With some big gaming companies exploring NFTs, where does Factorio stand?

We are a games company based in the Czech Republic. Russia's invasion of Ukraine affects us directly. We have team members there, we have friends there, and we get information first hand. There is no excuse for the actions of the Russian army, they have little regard for civilians including children.

We support Ukraine and have made contributions to relief efforts.

We support Russians that stand against the actions of the Russian government.

You can help too, even if it is just with your voice. World leaders are listening: every voice counts.

The Czech National museum, which has bullet scars from the Russian invasion of Czechoslovakia in 1968.

Please, keep the discussions about the world events (if you can't help it) specifically in threads related to this post, as we want to keep the rest of the content on topic.

Hello,

Today is actually the 6 year anniversary of Factorio launching on Steam, and just recently too we passed 3 million total sales (and we're even past 3.1 million at this point), so it is quite a milestone. It is great for us that the game is still selling consistently year on year, even though we never take part in sales or bundles.

Hello, long time no talk, we've got some catching up to do...

Almost 1 year ago we said "we don't think that will take less than a year to develop". Well it has been less than a year and it is not finished, so we kept our word on that :).

But while it might not be finished, there is a still a lot we have done so far.
