The new terrain sounds interesting: Dunes are blocking terrain that imparts a movement penalty (like forests without a cover bonus?) Crevasses are impassable and appear to break up some maps significantly, limiting one's options when crossing the map. Dirt roads are like normal roads except vehicles get double instead of triple movement along them.
Also, the article mentions the lack of forests creating longer lines of sight and less cover - sounds like a meat grinder to me.
And - this is news to me - there are new specialization tokens! Anyone know anything about this?
