Hi Guys, I used to play Combat Mission all the time back in 2003 and 2004. I had all three games: Beyond Overlord, Barbarossa to Berlin, and Afrika Korps. I want to dust these games off and get them going again. Are there any recommendations where to start in terms of installation and patches. Hasn't the whole game been improved? Any assistance or direction is appreciated. Thanks and have a good day!
