Anti-Air Battery 2 is a location in Xenoblade Chronicles. It is one of the three Anti-Air Batteries in Colony 9 used to protect Colony 9 from falling Mechon debris, along with any potential Mechon invaders. It is to the northeast of the main part of the Colony, and north of Agora Shore. This location can only be reached by swimming. It is surrounded by Throne Sardi and residence to six Resplendent Flamii. To the north of it there is an unnamed shore, with more Resplendent Flamii, as well as some Opulent Flamii and the Flailing Bracken.

The two Fallen Objects required for Presents for Priceless Pupils can be found here (one on the shore, and one on the battery itself).
