Hello everyone,
Just a very short post. We, the Factorio team, would like to wish you all very Merry Christmas. Take the opportunity to have some rest and recharge your energy (we certainly will). We have also prepared a small present for you. It is a never-before publicly released prototype of the game from the autumn 2012, so it is more than a year old. It is from so long ago that the game was not yet called Factorio. At that time we provisionally called it Energycraft. There are only the win32 and win64 binaries available (you can use emulator on other systems). Bundled with the game are 2 saves from that time, so you can have a look at some existing factories. Playing that version even for couple of minutes brings back a lot of nostalgia:) Merry Christmas everyone!
