Space Engineers servers have many editable settings from the config folder. One popular setting is the gravity strength on individual planets. Changing these values can let players fly around at low gravity, even on Earth-like planets, or have a heavier gravity on far-off moons. It's worth noting, however, that with higher gravity comes a higher cost when leaving the atmosphere in a ship, with heavier gravities making ship launches much more difficult.
Note: Make backups locally to save any necessary files.
1. Log in to the BisectHosting Starbase panel.
2. Stop the server.
3. Go to the Files tab.
4. Find the following directory: /home/container/config/Saves/World .

6. Right-click the downloaded file and select Edit with Notepad++. Download Notpad++ here.
7. Press Ctrl+F to bring up the Find menu.
8. Type surfacegravity into the field, and choose Find Next.
9. Replacing the <SurfaceGravity> number will change the gravity modifier for that planet. The planet's name is listed a few lines below.
10. Cycle through planets by selecting Find Next again in the find menu.
11. Once finished editing, choose File > Save from the top-left.
12. Return to the BisectHosting Starbase panel.
