Alpha funding! Early access, alphafunding, or paid-alpha is a funding model in the video game industry by which consumers can pay for a game in the early stages of development and obtain access to playable but unfinished versions of the game, while the developer is able to use those funds to continue work on the game.

Factorio is a game in which you build and maintain factories.

You will be mining resources, researching technologies, building infrastructure, automating production and fighting enemies. Use your imagination to design your factory, combine simple elements into ingenious structures, apply management skills to keep it working and finally show your combat skills in encounters with creatures who don't really like you.
