Two major fronts/ Maps/ sets of multiple maps could be added to Moscow Campaign.
This would give the campaign a “revival boost” and more depth while staying historically as accurate as possible with the current limitations provided.
- Brest Fortress.
Germans wanted the fortress because there was a railway choke point that they desperately needed, therefore this set could include the fortress itself and a railway/ logistics place connected to the railway. (At least 2 maps, with further work 3-4 new maps)
One of the most famous stands that the Soviet Union did on the front-lines, still a historical place where Belarusian s visit very often a tourist attraction for the population. Very heavily fortified area that would provide some fortress fighting for the Moscow Campaign.
- Leningrad siege.
Terrible nightmare that unfolded in the beginning of the operation of Barbarossa, KV-1 tanks were driven directly from the factory floor to the battle as soon as possible, some of them were not even painted.
Leningrad area could be filled with many trenches that need to be stormed, Soviet counter-attacks, night fighting and ice-road.
Plenty of new map material there too, should provide 3-5 maps.
Also as a BONUS suggestion, new weapon (Premium and expensive like Suomi-sub-machine gun in Moscow Campaign)
Lahti-Saloranta LMG (Widely used by Finns)
