Hello, actually I'm working on Stalingrad campaign as you perhaps know. 
 

 The first step is to add some specific elements to Stalingrad: ruins, industrial buildings, factory, ...
Grain Elevator :
 
 
Industrial buildings:
 
 
Train:
Fuel tank:
I'll add more factory, specially the large ones. 

 Ruins, debris, new trenches, shell hole, ditch, ... are already planned :
Ruins:
More ruins: (we need a lot of  

)
Shell hole:
Ditch:
Factory:
 
 The Second step is to add some new units if necessary. Any suggestions?  
  
 
 
 And the third step is to see how render the urban combat and the house to house tactical. In a perfect world/game we need to have different floors for the large building. But I guess I can't deal with this features... So here again all suggestions are welcome!
