A briefing from the developer:
(...) it took us a full two years, from the game's original release in 2011, to complete the Eastern Front trilogy with a Barbarossa campaign. (...) The campaign is longer than "Stalingrad Campaign" and it flows more naturally from easier to harder, as the fortunes of war change for the invading Wehrmacht.
So, we go from the dramatic early victories all the way to ignominious defeat at the gates of Moscow? Well, yes and no. Certainly, we like to stick to history, and the first 10 scenarios of the Axis campaign take you from the violent frontier battles, through epic moments like the Kiev Encirclement, all the way to Taifun, the final German assault on Moscow.
This final historical scenario is an 18-turn, 200-unit behemoth that is rated "hard" to boot. You may as well lose here, but then, the Germans didn't win either. In case you do manage to take Moscow however, there are two further what-if scenarios. There's no point in spoiling this for anybody so just briefly: the what-ifs are challenging and only slightly ahistorical. We've also made the point of doing some novel things with the AI there, as an indication of what lies in the future for 2×2 games.
The story of the 1941 campaign wouldn't be complete without a telling of the Soviet counterblows that followed. The Moscow Offensive, in December 1941, is when the Red Army finally relieved the pressure on the capital. What followed immediately afterwards was the January Offensive (of 1942), a typically ambitious attempt to encircle and destroy most of German Army Group Center. It wasn't a success for the Soviets, but rather a bitter and confused struggle that ultimately resulted in the creation of the famous Rzhev salient. Can you do one better for the Motherland?
We shall find out come December 10th, the appointed date for Black Turn's release.
