The Alien Glyph Carver is seen in some parts of the Hierarchy Campaign, though it is not seen as a unit in the game, unlike the Manipulator.
It has a transparent skull, similar to the Manipulator, and internal organs are slightly visible in the picture to the right.
- It is thought that the Alien Glyph Carver (AGC) was supposed to be the Glyph Carver in the game but was changed to a machine instead.
- Another theory is that it was the pilot of the Glyph Carver. This is probable, since Orlok the Eternal mentions Glyph Carvers in his rebellion speech.
