Weapons Research Facility T12A was a UNSC research and development facility located on Algolis.[1] It was operated by the UNSC Engineering Corps.


Human-Covenant WarEdit

At an unknown time during the Human-Covenant war, a marine nicknamed "Ghost" used the Prototype Powered Exoskeleton housed inside the facility to fend off Covenant forces as a last stand. After the surviving civilians and Marines evacuated the facility, Ghost initiated the Exoskeleton's nuclear fission self-destruct sequence to prevent the capture of the suit's technology. The resulting nuclear blast destroyed the facility along with all Covenant ground forces on the planet, including "Ghost."
