2 Banshees, 3 Chirons, 2 Scourge Champions, an Alpha Tyrant, Alpha Ghoul, and Alpha Shieldbearer plus some change at night in the first 5 turns is more than hard. I mean, it’s doable, but it definitely creates the “hey man, can I please go get a crate now” feeling.
I would classify this difficulty as extreme.
Phew, made it with no losses, but only because of the Aspida I brought along. That’s the most full restores I’ve done in a single mission.
