Alright, just to let you know before hand, i have beaten the game on all skill levels. I just wanted to see what the cheats were like, what the game would be like with them, i added the +set monkeytoy 0 +set sv_cheats 1 to the target field, but it says its not valid. so i need to delete the quotes around the original text that is in the target field?
you have to make a shortcut and put +set monkeytoy 0 +set sv_cheats 1 in the targer field without the quotes. the i game open console and type in the cheat u want.
For more info, here's a good site I found:
