I'm just curious, what do you mean by CoH retro mod? When making this thread, I was myself attempting to clone CoH1 into CoH2. I managed to create the USA Headquarters (and all units/upgrades), Barracks (all units and ugprades), WSC, and Motor Pool (all units and upgrades). I also created a functional doctrine system, and finished the creating the Airborne doctrine. It was quite tedious producing all the weapons, especially since each has a unique target table with over 40 entries. I've since been slacking for the last 3 months and haven't touched it (since my mortar barrage failed to work, sniper was being buggy, and I couldn't get a visual gunner on my M8). How's your progress going? Any chance maybe on doing a collaborative work?
