The factory creation sim genre was one I didn’t know I needed until Satisfactory came out back in 2019. With Satisfactory Update 4 finally here, it’s time to pick up a planner and get to work.

Coffee Stain Studios sure knows how to keep bringing players back for more. Between games like Viking survival simulator Valheim and factory production/management simulator Satisfactory they certainly understand what it takes to keep a player base.

Satisfactory Update 4 is finally here after over a year of waiting following Update 3. There’s some big stuff in the patch, so here’s everything you need to know about Satisfactory Update 4.

What’s next for Satisfactory?

I think it’s safe to say that Update 4 is going to satisfy players for the time being. It’s huge and there’s enough in there to keep us busy for quite a while. Despite that, players are always wanting more. Update 4 has been highly anticipated ever since Update 3, so you can expect people wanting Update 5 soon.

That said, as mentioned above, it’s been over a year between Update 3 and 4 so we aren’t going to see 5 for quite some time.
