The Axis is opposing forces against the Allies.
They are one of the two opposing factions in the Multiplayer aspect of Return to Castle Wolfenstein and Wolfenstein: Enemy Territory, and the enemy of the Allies. The Axis also appear as the opposing force in Wolfenstein RPG, represented by the German army (Axis is used as Nazi symbols are censored in the game).
The Axis powers (German: Achsenmächte, Italian: Potenze dell'Asse, Japanese: 枢軸国 Sūjikukoku), also known as the Axis and the Rome–Berlin–Tokyo Axis, were the nations that fought in World War II against the Allied forces. The Axis powers agreed on their opposition to the Allies, but did not completely coordinate their activity. The Axis grew out of the diplomatic efforts of Germany, Italy, and Japan to secure their own specific expansionist interests in the mid-1930s. The first step was the treaty signed by Germany and Italy in October 1936. Benito Mussolini declared on 1 November that all other European countries would from then on rotate on the Rome–Berlin axis, thus creating the term "Axis". The almost simultaneous second step was the signing in November 1936 of the Anti-Comintern Pact, an anti-communist treaty between Germany and Japan. Italy joined the Pact in 1937. The "Rome–Berlin Axis" became a military alliance in 1939 under the so-called "Pact of Steel", with the Tripartite Pact of 1940 leading to the integration of the military aims of Germany, Italy and Japan. At its zenith during World War II, the Axis presided over territories that occupied large parts of Europe, North Africa, and East Asia. There were no three-way summit meetings and cooperation and coordination was minimal, with a bit more between Germany and Italy. The war ended in 1945 with the defeat of the Axis powers and the dissolution of their alliance. As in the case of the Allies, membership of the Axis was fluid, with some nations switching sides or changing their degree of military involvement over the course of the war.
The Axis represents Nazi Germany in Multiplayer. Their weapons and uniforms are distinctively German, yet without any of the controversial Nazi imagery, which could cause the game to be forbidden or censored. Their insignia is a white RtCW logo on a red background.
In most Multiplayer scenarios, the Axis is traditionally on the defensive, trying to prevent the Allies from stealing something valuable (e.g. treasure, ancient relic or secret documents) or destroying an important objective.
