[ТУРНИР HMM IV OFF] " New World "

When executing a specific code, if the script doesn't understand where you got it from or how you managed to do it, it will assign you a variable. After that, on the next turn, you'll receive a message about defeat.

I'm expecting more fun – it's a long and tedious process to explain to the script "how I managed to do it." :D
And if it turns out to be uncooperative, it's easier to find the variable in the save file and insert the correct value.
No, I'm not really excited about that prospect. For protection against cheating, the accepted norm here seems to be quite sufficient: "submit save files and explanations!"

Yes, there's a lead regarding Prometheus. If you enable a cheat, plot a route for an army into a "black" area, and then save, that save file will indicate the use of code. Loading it with "Prometheus on" and "Prometheus off" shows the difference – "there is a route" and "there is no route."
Although I don't see a major problem with playing on an open map, I'll still note: you need to end your turn with the cheat turned off; otherwise, the open map may change the behavior of the AI.
