Civitas Scenario Editor

An unofficial fan tool for Civitas: World Simulator. It runs entirely in your browser - your files never leave your computer, and nothing is uploaded.

Click Open scenario file… (or drag a file onto this page) and choose world-1936.scenario.json.
Edit nations, identities, flags, leaders, wars, armies and more.
Click Save for the demo, then put the saved file back in the game's Scenarios folder.

Not sure where the file is? In the file dialog's address bar, paste:
%USERPROFILE%\AppData\LocalLow\Wrenchy Production\Civitas World Simulator\Scenarios

Save

The demo only plays "World 1936". Save for the demo gives you a world-1936.scenario.json to put in the game's Scenarios folder, replacing the old one.

Separate scenario (full game)

Saves a new file with its own name, for the full game's scenario list.

Saved copies (kept in this browser)

Every file you open is backed up here automatically, so you can always get the original back. Nothing leaves your computer.

Map image (optional)

To see unclaimed land, load the scenario's map image. For World 1936 it's 19308k.png in the game's StreamingAssets\Map folder (it isn't included here).
