Wikipedia states that there's an ending with both AM and lunar colony destroyed. Have you ever reached it? If so, how?
To reach that ending you must neither disable all parts of AM, which you need to do to get the good ending, nor just disable the Ego as the Russian and Chinese computers want you to do.
Disable only the Superego, the Id or the both of them.
When you then return to the Russian and Chinese computers, they will be angry at you because you were disobedient and created a stalemate between them and AM.
If you now use the totem of entropy on them you will achieve a phyrric victory. You disabled enough of AM to destroy him, but a remnant part of AM will kill the lunar colonists by disabling the life support systems.
