Anti-Air Battery 3 is a location in Xenoblade Chronicles. It is located in Colony 9. It is one of the three Anti-Air Batteries used to protect Colony 9 from falling Mechon debris, along with any potential Mechon attacks. It is located south from the Tranquil Square in the Residential District. It can only be reached, and therefore discovered, by swimming there.
The Dark Murakmor can be found on the slope of the Anti-Air Battery, at night.
