This difficulty aims to make the game tougher in a fair and learnable way. It requires lots of awareness and skill.
For comparison's sake, I believe this is the hardest, below that of Armageddon, however you can configure it to be much more difficult, pretty much impossible.
It should feel a lot more like the planet doesn't want you here, and is there to obliterate you. You are likely gonna get swarmed.
Note: Other mods that change enemies/directors might not be compatible with this difficulty.
