We have uploaded a Scenario Tool for the game! You can use it together with the in-game Scenario Editor to edit and create new scenarios. It shows you the scenario file contents in a table-like fashion, making it easier to edit large amounts of data.
Be careful not to overwrite your original game files. We suggest you use in-game Scenario Editor to create your own scenarios in Custom Scenarios folder. And then you can use this Scenario Tool to edit your custom scenarios.
Have fun!
