First, a quote from The_Chieftain on 8.6 (27th April, 12:05):
Well, I've seen the 8.6 notes, and they are far more significant than I had been led to believe. Arty is, as the devs on the Russian forum reported, getting a major re-work, some things I think are good, some not so good. We'll see how it pans out. Arty isn't the only thing getting significantly changed either. The 'nuclear' comment is somewhat justified.
Now I am curious :) Truth to be told, I expect some change of gold-ammo-for-creds type: useful for some but controversial for others. Sexton I and Excelsior are also scheduled to appear.
