Panzer Rollen is a WW2 tank game. You can fight with British Cromwell, Firefly, Russian KV-I, KV-II, T-34-76, T-34-85, T-35(multiple turrets), BT-7, German Panzer-IV, Sdkfz251(half-track), Tiger-I, Japanese Type-89, and Finnish BT-42. I will add tanks and historical missions in the formal version. In the demo version, I used Physics Tank Maker.
