Codename: Panzers

Like Soldiers: Heroes of World War II and, to a lesser extent, Blitzkrieg, Codename: Panzers focuses on managing groups of troops, tanks, armored vehicles, and artillery and destroying the enemy or capturing objectives. The game abstracts concepts such as supply, repair, and air support without doing away with them entirely, and belongs to the real-time tactics genre more than the traditional wargame/simulation genre.

Units gain experience throughout the single-player campaigns and can be bought/upgraded between missions and added to the player's personal 'army' that travels with them from scenario to scenario. Completing mission requirements and optional objectives gives the player 'Prestige' points, which can be accumulated to upgrade existing units or used to add new units to the player's core force. Additionally, many missions provide the player with extra units to complement their core army. Also, the player is most often responsible for keeping alive a single 'hero' unit.

Codename: Panzers focuses on three campaigns: German (led by Hans Von Gröbel), Soviet (led by Aleksander Efremovich Vladimirov), and Western Allied (led by Jeffrey S. "The Buck" Wilson and James "The Gent" Barnes). The German campaign begins with the Blitzkrieg of Poland, France and then the invasion of the USSR, with the final campaign mission at Stalingrad. The Soviet campaign begins with the turn at Stalingrad and ends with the Battle of Berlin and the capture of the Reichstag.

The Western Allied campaign begins with Operation Overlord and the Normandy landings, and includes battles such as Operation Market Garden and the Battle of the Bulge. The game features realistic representations of tanks, artillery units, air forces, and infantry from Germany, the United States, the Soviet Union, Britain, France and Poland. It also features Yugoslav partisans fought in the German campaign when the player moves through a rebellious area of Nedić's Serbia.

The game received "favorable" reviews according to the review aggregation website Metacritic.

In the German market, CDV expected the game to succeed. The company planned an opening shipment of 90,000 units to retailers, and ran an advertising campaign on television with the stated goal of reaching "beyond the usual hardcore-gamer confines". The game debuted as the region's top-selling full-price computer game of June 2004, according to Media Control. It sold 66,000 units in the German market in just under two weeks, and 70,000 units after 15 days.
