In the semi-canon video game Lost: Via Domus, Elliott Maslow discovers "The Incident Room" on the other side of the concrete wall. The Incident Room was accessed by a tunnel and a large locked door near the exterior of the Swan. Although the videogame is considered non-canon, the Incident Room is canon since its location was verified on the blast door map.
The room contained a large reactor amongst a room full of severely damaged equipment. The reactor is tilted to one side, and discharging electricity and a fluid that looks like water. The reactor had the appearance of two large electromagnetic coils suspended over an excavation into the Island. Unlike the Swan, the Incident Room's machinery is in a state of disrepair, possibly due to the Incident. The Incident Room also has its own computer, much like the Swan's.
