The Hazen Facility is a Normal factory featured in Armored Core 4.
Constructed by GA America, the Hazen Facility is a Normal AC factory located in California, United States. It becomes occupied by a terrorist group during the events of AC4, but is later cleared and recaptured by GA thanks to Anatolia's Raven. Rayleonard's Original Anjou would later meet her end at the Raven's hands within this facility.
- The Hazen Facility reappears in Armored Core: For Answer as a multiplayer map named "Normal Factory."
- The facility is located at the foot of Mt Charleston in California, and is presumably accessible via the Veterans Memorial Highway.
