I've written this guide in a way that should hopefully work fine without actually enabling displaying of file extensions in Windows. You don't have to follow it word for word, if you know what you're doing. Also don't expect this guide to work on Windows XP.

Before we start, make sure to run the game at least once and quit it, so that the config file is created. After that, quit the game.

Now press Windows Key + R and in "Open" field type in:

Alternatively you can open Windows Explorer and navigate to this location, which when solved would be:

Now make a copy of machine-config.cfg and name that copy config.cfg (or if you know how file extensions work, create a new empty file under the name config.cfg).

Now open config.cfg with a basic text editor like Notepad++ (at worst Notepad will do... just don't use Word, ffs).

Delete its content and add following lines and save it:

Launch the game and load a level. When you press ESC, on the top there will be a Cheat Menu now.

Here is a bunch of console commands that can be used to figure out AI behaviours and overall test the game (for speedrun routing mostly). As in most engines, the console command is opened with tilde key. Console commands are provided in the same order as they are initiated in game.
