Its released in early access last month.

Game will have content updates at the end of April and next time month later, etc. They have said that Satisfactory is in early acces approx for a year.
Have to say, very good early access, havent found any bugs and gameplay is very smooth.
Currently you can play until Tier 6 and i have restarted once as the first try grew impossible to continue because i began building at bad location. Made also some poor decisions in the planning and it would have been enormous task to rearrange all the conveyor lines.

Wanted to start again also after i learned the mechanics and how stuff works and planning was way easier at the second time.
