Extravagant Underground is a new stage in Tekken Tag Tournament 2 and Tekken Revolution. It takes place in Russia at a metro station. Due to the stage being located in Russia and the BGM name, one can assume it is possibly Sergei Dragunov's stage.
The stage BGM is called "Mystic Force".
- This stage was also used in the TTT2 Gallery Mode.
- The station name is Серебряный медведь (Silver Bear).
- The station and the whole metro system (according to the map on one of the walls) is purely fictional.
- However, the map bears resemblance to the Moscow Metro map.
