Fallen Garden is a stage in Tekken Tag Tournament 2. It corresponds to the Heavenly Garden stage. Unknown is subsequently fought here as the final boss in Arcade mode/Single Player mode. It is the corrupted version of Heavenly Garden, due to the power of Unknown (after the defeat of Jun Kazama in the first round). The stage has rapidly deteriorated, thus causing the plants to become wilted, changing the clear water into thicker, purple liquid slime, and turning the sky dark and twisted. The flamingoes are gone and the flower beds now appear to be set ablaze in the background.
- The stage BGM is called "What You Will See -Hell-".
