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of the gameplay being changed and adjusted, and if we tell you about them now, the information would quickly become outdated and inaccurate.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.
