To access cheat codes you need to open the console. To open the console press the "Scroll Lock" button on you keyboard, also known as "Scr Lck". When the window pops up everything you write will come as text in the box. Do not panic if you cannot play anymore, just simply press the same button you used to open it, "Scroll Lock".

To access the cheat codes simply type "GreatStuff" in the console.

If you dont want to do "Shift" + "Tab" to see this all the time, you can simply write "/?" after enabling it.
