We found this thing buried in the glacier. Gave someone a hell of a fright.
Turns out it was walking around a thousand years ago when it fell through the ice. It was infected with the Kharaa bacterium - the aggressive disease which wiped out the architects and almost life on the planet. It is unclear whether the mutated Kharaa pustules present are responsible for the ultimate demise of the creature.
Since the enzyme cure was released on 4546B the bacterium has been all but eliminated. Rare specimens like these provide our only live source.
Research on the bacterium has been transferred to the secure Omega laboratory, while further research on the creature will be conducted at the excavation site.
