Secret Laboratory is a stage introduced in Street Fighter IV. It takes place on an unknown island on the North Atlantic Ocean, between the United States and North Africa.

This is the stage where the player fights Seth as a final boss.

Zoomed out view of Secret Laboratory.

This is the laboratory of S.I.N. There are experiments made in this laboratory that can be seen with camera mods, with two test experiments one male and one female. It appears that the equipment is being pushed to it's limits as there is smoke coming out of some of the machines and others are shaking as if they are under heavy use. On the sides there are doors with S.I.N. symbols that is not known where they lead to. On the machine in the center of the stage, there are steps that lead to the second floor of the machine, however there is no more computers or other electronics on the second floor.

Trivia Edit

  • Off-screen there is a computer that shows stats for an unknown humanoid. The page is very similar to a background element in Capcom's Resident Evil 4 that shows X-Rays of an unknown person who appears to be Ashley. There is also an off-screen door that the pathway and door shape itself is reminiscent to the door that the Zealots take Ashley in early chapters three and four.
