Combat Mission: Barbarossa to Berlin (CMBB) is the revolutionary successor to the award winning game system pioneered in Combat Mission: Beyond Overlord. Bigger, bolder, larger in scope with layers of more detail, it is the epitome of the state of the art in combat simulations.
Combat Mission: Barbarossa to Berlin is a 1-2 player, hybrid turn-based/realtime 3D simulation of WWII tactical warfare on the Eastern Front from 1941 to 1945.
Experience combat in a full 3D battlefield as tracers arc overhead and exploding shells shake the earth! Feel the tremendous power of the feared Russian Katyusha rocket barrage! Order a tank hunter team to assault a heavy KV-1 with Panzerfausts and magnetic mines in the ruins of a shattered city! The fluid game interface combines with 3D lines of sight, misidentification of targets, enemy detection by sound, advanced armor penetration systems, unit morale and leadership effects, spreading fires and billowing smoke, wind and weather and much more to bring you unprecedented realism in a computer simulation.
