[HMM IV OFF TOURNAMENT] "Spring Mobilization"

Can anyone answer about Warlords IV?

I think they will be held on regular War of the Whirlwind maps.

Yeah, and spend another month studying its features. How is it different from War of the Whirlwind?

Hmm... the gameplay becomes much more interesting when the computer thinks a little bit. And in general, there should be details about what exactly this add-on changes on the official website.
