Bethlehem Medical Centre Sub-level Three connects Psi-Obs and the secret exit to the Rail Tunnel as well as a number of storage bays and offices to the rest of the facility. It is one of the more secure sections of BMC, with the access to the Psi-Obs BMRI protected by multiple security checkpoints, including a blast door.

Development Notes: Sub-level Three was built in January of 2007, a year after Psi Obs, which is connected to to it. Unlike the compartments of the Daedalus and the Sabrosa that connection is much like a Hollywood set – everything you see in the climax of The Dualist is one environment, while Psi Obs is another. Much like Sub-level One I created a floor plan in Photoshop, traced it with the pen tool, exported the spline, extruded it, then punched holes for doors.
