Would love to see tracer being fired between the buildings to make it seem soldiers are in the buildings fighting etc.
I think certain areas need to have less snow and more craters, around the Factories for instance, constant fighting and bombardments during November meant snow had little chance to settle around those areas. Also trenches going between the buildings, with over head cover in some parts etc etc. Plus some streets where pretty impassable due to rubble. More rubble is needed I think.
Lots of wrecks aswell could be placed especially transport types.
