I'm still near the beginning of the game but tried using God Mode as a test - in case of future need ;-)

I can access the console window but when I type in "God" and then hit Enter I'm told "Command cannot be executed. No valid script function available".

So can I not use God Mode with this GOG version ??

the console is case sensitive and the command is "god".

Thank you SO much. [I tried "god" and it worked.]

I got the cheat instructions from .. cheatcc.com .. and their site shows "God".
Which seems rather poor :-(

Anyway, thanks again.

EDIT :
Since looked at several cheat sites and they all quote "God" !!

Most likely a bunch of different sites just copy+pasted the cheat list from the same source.
