After playing for dozens of times, I found the best chance to beat Mega Brutal in Saffron Fields is choosing advisors Journalist, Foreign Minister, Credit Manager, Private Donor, Drill Sergeant and Censor, start at Delta Yankee and hoping the insurgents don't attack Delta Uniform or Echo Tango before the first solider unit is ready, the HQ region does not demand for jobs or infrastructures, and no negative or expensive random events at early game. That's a lot to "hope" for, therefore the RNG God, not my skill, will decide I win or loss.

Beating Mega Brutal in Saffron Fields largely depends on the RNG God, and other maps are practically impossible.

The Soldiers are very slow to train and more expensive comparing to regular games, so at the very beginning of the game the player (me) has no choice but spend value funds on two Solder units. That means less funding on civilians initiatives, and will have to let the RNG God decided whether the first zone can stabilise before losing the game due to lack of stability.
