I was having a hard time on one of the levels so I checked out Dungeon Keeper 2 on GameFAQs and apparently there's a cheat mode if you press Ctrl & Alt & C at the same time, but I can't get it to work.

I've tried different combinations of both left and right side keys, but for some reason it's not working.

Am I doing something wrong or does the GoG version of Dungeon Keeper 2 not have any cheats?

hold dow cntrl + alt +c
and you'll hear a soft "clunk"/ door opening sound

then type in the cheats exactly as written ( using _ to denote space-bar)

ie
ha_ha_thisaway_ha_ha_thataway
- for 100,000 mana

feel_the_power
- all creatures level 19

show_me_the_money
- fill all your treasure rooms with gold.

see here for the others

You have to do this in the pause menu and then it will work.

doesn't work at all :(

Ok here's the deal I'm in the pause menu and I hear the door sound but when trying to type a code in the door sound plays again. I saw someone say that you have to use _ for spaces but as soon as I hit shit the sound of the door closing happens. I've tried no spaces and just the space bar but the sound of the door always happens long before I can finish typing a full code. What am I doing wrong?
