Moscow to Berlin: Red Siege

Moscow to Berlin: Red Siege is a 3D real-time strategy game set during World War II. It is a stand-alone add-on for the game Desert Rats vs. Afrika Korps. It's built on the same engine and thus features similar gameplay and graphics. In three campaigns that link a total of 20 missions the player each time controls a small predetermined selection of units ranging from infantry to tanks and artillery. During a mission you might also receive reinforcements, but you have no say in the type of units you receive. Units can gather experience which improves their performance in combat. This time you play as the Russians or the Germans (depending on the mission) in various battles of the Eastern Front. Both sides have different units to a total of around 80 unique units. An included encyclopedia describes each of those units in detail.
