I happened to be looking through the game files today, and I noticed this:
I’d never seen a dcam campaign file before to my memory, and it doesn’t have any typical campaign files like the others, so I extracted it. And what do you know, I find these:
And as it turns out, the first appears to be the Mongol Raiders scenario, and the second is the Barbarossa Brawl.
So were these always here, and I only just noticed them, or is it possible these are going to make a resurgence in the near-ish future?
This reminds me that they had promised that these Challenge Scenarios will return. I hope they add them soon and bring new Challenges too. These scenarios were much better than the events they add every month.
They were in the game files the whole time but not accessible in-game.
One year ago the devs wrote this in the patch notes of update 40874:
While the Barbarossa Brawl replaces the Mongol Raiders scenario, don’t worry; we’re working on a home for all the scenarios and leaderboards in the future!
