The deceloper console allows you to manipulate aspects of the game. This is a hidden menu created by a game developer to allow them to test aspects of the game without having to do a full playthrough. This page will detail the available commands and their use.
Opening and closing the console
To open the developer console ingame you have to enter 4,1,2,3,6,9,8,7, O (capital letter O) on the number pad. The normal top row numbers don't work. To close the console use the "X" in the upper right corner.
Available commands
For an overview of the possible commands enter -help in the console and confirm with ENTER. The “hyphen” must always precede each command.
