Satisfactory Update 4 – Patch Notes and Reactions

Satisfactory Update 4 – Patch Notes and Reactions

Apr 13 Masonzero  

I don’t know about you guys, but I’ve been playing the heck out of the Update 4 on the Experimental branch. Luckily I can now stop staring at the big red ribbon in the corner, because the update has come to the Early Access branch! You can now load up your Experimental saves in Early Access and continue your adventure with this full update release.

As usual, we’ve copied the patch notes below, and we’ll comment up here about some of the highlights. Of course the new content is great, but we’ve already discussed drones, lights, and new production lines, so we won’t be dwelling on that. We’ve already created a video tutorial on nuclear in Update 4 and how to use drones, so click the linked text there to watch those guides.

Lights are very exciting and I’ve been enjoying using them in my enclosed factories. They work really well, and it’s nice to see that the developers found a way to implement them in a way that doesn’t cripple game performance.

Coming over from the Experimental branch, some of the best new updates are the upgrade to the new game engine, the rebalancing of nuclear and aluminum production (they’re easier now), and the increased stack sizes for commonly used items.

It’s nice to see some major improvements to performance. This includes a new system for rendering items on conveyor belts, a reduction in overall bandwidth consumption, and new imposters for buildings (which reduces how complex buildings are when rendering in the distance). Overall there are a lot of great optimizations, most of which I’m not smart enough to understand completely – but I trust that they’re working!

Most importantly, the lizard doggo has more animations now.

Patch Notes


  • Updated to Unreal Engine Version 4.25


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


  • Aerial Resource Transport
    • Drone & Drone Port
      • Let Drones fly your resources across the map in Tiers 7&8. They are most effective over longer distances.
  • Lights
    • Ceiling Light, Flood Light Tower, Wall Flood Light & Street Light
      • These 4 buildables will allow you to finally illuminate those dark factory floors.
    • Lights Control Panel
      • This panel can control the settings of all lights connected to it.
  • Equipment
    • Hover Pack
      • This new equipment allows you to fly through your factory wherever you have a functioning power grid.
    • Zipline
      • It allows you to attach to Power Lines and zip up and down them as much as you want.
    • Buildings
      • Blender
      • The next level of fluid related production allowing you to combine up to 2 fluid and 2 solid resources
    • Particle Accelerator
