Laboratory is a stage in Tekken 4. This fight takes place inside a locked-down laboratory room hence the stage name. There is steam near the ground which is coming from vents below. Its appearance is close in relation to a vault or a chamber of sorts.
The stage BGM is called "Fear".
- In the side game Tekken Force, the first stage known as the "Military Compound" takes place in a different section of the stage.
- However, the BGM for the stage is the Mall stage theme, "Uninhabited".
- This can be the 5th or 7th stage in Story Mode.
