Console Commands
From Terra Invicta Official Wiki
The game's console can be enabled by editing the following file in the game's folder with a text editor: TerraInvicta_Data\StreamingAssets\Templates\TIGlobalConfig.json
In the second half there is the following line: "debug_ConsoleActive": false,. Set it to true and save the file. Note that certain game updates might overwrite the file, requiring another edit.
The console can be opened with the ~ key.
