Borealis



The Borealis is a scientific research vessel owned by Aperture Science. It first appeared in Half-Life 2: Episode 2, but a reference to it can be found in Portal 2 as an easter egg hidden in Chapter 6.

Overview
The Borealis is an experiment ship that holds legends about the rivalry of Aperture and Black Mesa.

The Borealis is one of Aperture Science's experiments including an immensely big portal technology. Someday, the portal malfunctions and now is stuck somewhere in the arctic regions. As said by Dr. Kleiner that parts of the dry dock is carried away, this is partly false because when the player reaches the location, it is intact, partly. The cranes, tethers and any equipment linked to the ship is missing.

Portal 2
In Chapter 6: The Fall, the Borealis' drydock can be found in Test Shaft 09,. It is hidden behind a door in one of the offices and, while the drydock is empty, life preservers with the word 'Borealis' printed on them can still be seen.
