Of course, there's a place to find out. ) Am I right in understanding that they added a new campaign, among other things?

No, there's no campaign this time. There's a random map generator, even improved compared to the usual one. They did a good job with the balancing. In general, we're slowly exploring multiplayer horizons.)

P.S. Most likely, we'll create a topic about the project later in the section dedicated to the classic trilogy. It seems a bit out of place here, as the addition isn't related to Heroes and can't even be installed on it - and the topic is hanging in the subforum for some reason.
