M-series facility

M-series facilities were Forerunner facilities of unknown purpose. According to the Bestiarum, all Huragok under Covenant employ were from M-series facilities.

Trivia

 * Halo: Cryptum describes Huragok as serving aboard semi-automated maintenance stations; as such, it is possible that these are M-series facilities, with "M" possibly standing for "maintenance."
