  • Changed the way the game is packaged to make it more mod-friendly. This shouldn’t have a significant impact on anyone other than modders

As you can see, Satisfactory Update 4 is quite the content-heavy patch. Most notably, autonomous drones should provide another solid option for transporting your goods to and from. The same can be said for the hover pack and ziplines, which should give plenty of new ways to traverse bases. And of course, a whole host of new buildings should make Satisfactory Update 4 feel that much beefier. If you’re excited to try all of this out, trust me, you aren’t the only one.

Satisfactory is available now on PC in Early Access. For more information regarding this update, check out the game’s official Steam page.
