You can get experimental releases by selecting the 'experimental' beta branch under Factorio's properties in Steam.

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of the gameplay being changed and adjusted, and if we tell you about them now, the information would quickly become outdated and inaccurate.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