After a lot of work we have managed to release the first version of the demo. It is not graphically complete and there might still be bugs and issues, but we nevertheless decided to make it publicly available. Go and get it. The demo consists of a 3-level demo campaign which teaches the basic game mechanics, controls and concepts.
Together with the demo we made alpha version of the game available 'per-request'. The alpha version contains 2 additional campaign levels, freeplay mode and map editor. On top of that there are many more game elements which are disabled in the demo (different inserters, assembling machines, faster transport belts, solar panels, weapons, etc.) If you liked the demo and would like to try the alpha version let us know by email.
We wish you all the best in 2013 and we will work hard to bring you Factorio as soon as possible.
