Technical information[edit]

By making appropriate texture changes, altering Teleport_NewMap destinations, and by opening/blocking key areas as appropriate, this one map acts as the underground stations for all three of the hub's principal maps, Federation Systems Control, Language Labs and Classrooms and Launch Site.

The skybox and camera effects used to simulate the motion of the train were very new to the ZDoom engine at the time of development.
