Note: This procedure requires editing a game file; creating a backup copy of the file before proceeding is recommended. Start the game after selecting all desired settings. Exit the game. Use a text editor to edit the "SeriousSamHD.ini" file in the "\Serious Sam HD The First Encounter\UserData" directory. Look for the line:

cht_bEnableCheats = 0;  

...and change it to:

cht_bEnableCheats = 1;
