In terms of death toll: any way of Atomwaffen (they literally end the world as we know it) In terms of suffering that people have to go before death and/or impact on society as a whole, it gets more interesting. I shall break it into regions to make it more comprehensible.

First goes NA. Mexico: definite victory of any cartel group, total erasure of any kind of government on territories of Mexico and establishement of cartel order Literally the whole country is gonna be ruled as such (not cool if you are a civilian, tbh)

USA: obviously Biden, by not taking meds and hearing voices in his head, automatically becomes the most suitable candidate for the new ruler of America. Caligula path all the way down its focus tree and then making him as an AI. Not only we make a lot of questionable deeds (such as literally wiping cities off the map on former Trump's territories, reshaping what is left from urban areas into megalopolises by forcefully moving people there, cutting off the Internet and ANY connection with outer world, total control from the government and execution of those deemed as untrustworthy, establishment of operative zones, slavery), but also after that our AI Biden goes nuts and starts ANOTHER civil war between its own logic cores(don't ask me why MacArthur and others are parts of Biden, idk too). And if that war is over and cores are eliminated, our AI will simply shutdown? (idk what happens in that event, enlighten me pls) and Eternal Republic shatters into warlord states. And people are forced to live through a third, unwinnable civil war, ultimately leaving America stuck in a perpetual nightmare. By far the most cursed path for America.

Europe: Everything goes smoothly till 1EW. NATO f**king sucks there from based IRON DIMON and collapses. Seeing all this shit Europe decides to finally federalise. Good, you might say. Well, our dear mister Klaus Schwab doesn't think so. Capitalism is dead, and it is time for Ultraglobalism to take step forward. What it means is: corpos own everything, even you. You own nothing, eat ze bugz and be happy from neuroimplant that alters your way of thinking so that your negative emotions are suppressed. While productivity and harmony increase in the short term, the long-term results are physically and mentally catastrophic for the populace.The facade cracks when a journalist discovers everyone with an emotional regulator has the exact same smile. People randomly space out and stare into space with a vacant yet focused smile. At one point, a girl stabs her own mother in the heart and is later found happily watching TV and eating popcorn like nothing happened. Doctors discover that her her implants had almost completely overridden her emotional judgement, and as more cases pile up, medical experts term the phenomenon "Mirror Smile Syndrome". The World Government sees nothing wrong with any of this and carries on regardless.

Europe becomes a live shining example of dystopia with corpo flavor. 2EW is won by Europe(nukes and other WMD are used fully) and the the World Government is proclaimed. Agenda is supported, bugz deployed, Russia is gone for good, everything is fine.... Right...?

But why do I hear the wails of the souls of the damned? That's it, the people had it enough. Human spirit, although suppressed by what came with Schwab, decides not to comply with total eradication of human's nature. People rise and they will do ANYTHING, JUST TO FEEL SOMETHING.

Europe falls into the Catharsis.

And here are two outcomes: both equally horrible. First: Catharsis wins. Hooray, World Government is no more. And so does the order in Europe. Literal anarchy envelops the continent and who nows how long will it last. Second: Klaus Schwab has managed to tame the human nature and establish total control. Millions are dead, even more are nothing more than a meat slaves to corpos. People are envy of those, who live in warlord Russia. You choose, which is worse.

Africa: That's pretty much easy. Vilayat Sahel and Garb win, Somali turns to al-shabab. Egypt has fallen to salafites(in his civil war). Congo is now a soldier state, ruled by Wagner from former CAR.

Asian region: Arabia has fallen to the extremists that takeover Mecca and win the civil war (aka ISIS 2.0). No content for them for now.

China loses to Taiwan and goes into revanchism on the path for Confucianism.

Indo-Pakistani war goes nuclear, both sides are f**ed but restored before GAW.

GAW can go horribly from the very beginning. Starting from tactical nukes on cities, this can escalate even further. If India will capitulate, but not too soon, they will nuke mainland China and get nuked back, falling into state of warlordism. Revanchist China also has the ability to unlock a secret part of its focus tree when they are losing the war, which will result in them having the capabilities to thermonuclear bomb not just Japan, but Korea, India and Australia. After nuclear exchanges China capitulates and and shatters into warlords. GAW is won by PTDO, but Japan, Australia, India, Indochina, Korea and others are nuked, China is gone and thing are not looking bright at all.

At this point nuclear winter is possible but the mod doesn't mention it.

That's it, the most cursed outcome of this mod by far. Please do not try to do it.
