Sub Pen

General Information

The Sub Pen is a 2x2 Base Facility. You require one Sub Pen for every Flying Sub you own or are in the process of constructing.

Like the Air-Lock, the Sub Pen serves as an access point for encroaching alien forces. It also cannot be destroyed during a Base Defense mission.

This base facility appears in Terror from the Deep. For the UFO: Enemy Unknown equivalent, refer to the Hangar.
