How To Use

The command console is Factorio's command-line interface, which can be used for running cheat commands, as well as chatting with other players and receiving occasional status updated.

To open the console, press the / or ~ key. The ~ key is usually located below the Esc key. The / key is also usually the ? key.

The console can accept raw Lua code as well as game commands.

Use the Tab key to auto-complete commands and player IDs. Enter the first few letters and then press the Tab key.

Disclaimer: Because commands can sometimes make unexpected changed to your game, it is recommended that you save your game before using any commands.
