Looking for the space station? See Anchor 9.
Set in a UNSC Sabre engineering facility inside the refit station Anchor 9 in low orbit over planet Reach, this map features many close quarters combat sections. It is fully symmetrical with a two-leveled base at each side and a long spine separating the map into the "Weapons" side and "Repair" side. Both sides feature a large shield door that allows access to a narrow walkway outside the station for low-gravity combat.
