Secret Laboratory
LOCATION
A stage that appears in Street Fighter IV and its various incarnations, showing a secret lab operated by the SIN Corporation. The boss fight with Seth takes place here.


The Secret Laboratory is S.I.N. Corporation's headquarters, and also home to the final boss fight with Seth (Character) in Arcade Mode. There is a lot going on in this stage, from the reactor in the background that begins to go haywire near the end of the match, to the people in lab coats running back and forth, working on science and data stuff.
