# How to Enable or Disable Space Age DLC on Your Factorio Server (/docs/factorio/space-age)



import { Step, Steps } from 'fumadocs-ui/components/steps';

Space Age is controlled through `mod-list.json`, not server-settings.json. It consists of three mod entries:

Enabling Space Age [#enabling-space-age]

In `mods/mod-list.json`:

```json
{
  "mods": [
    {"name": "base", "enabled": true},
    {"name": "elevated-rails", "enabled": true},
    {"name": "quality", "enabled": true},
    {"name": "space-age", "enabled": true}
  ]
}
```

Disabling Space Age [#disabling-space-age]

Set all three to `false`:

```json
{"name": "elevated-rails", "enabled": false},
{"name": "quality", "enabled": false},
{"name": "space-age", "enabled": false}
```

> ⚠️ **Important:** Modify `mod-list.json` BEFORE the first server launch. Saves created with Space Age cannot simply have it disabled later.

> 💡 **Tip:** If the server keeps re-enabling the mods, delete the `space-age`, `quality`, and `elevated-rails` directories from the server's `data/` folder.
