You should see the pattern by now. Battlefield 3 gave us the Close Quarters pack to emphasize door-to-door combat and fighting in tight spaces with you and your team on foot. Now with Armored Kill on the way, it's time to open things up with aircraft and vehicles and this will require the biggest map in the history of the Battlefield franchise according to the talented folks at DICE. If you were able to get nice with your flight control in Battlefield 3, you're going to be all about Armored Kill as your air striking and hovering abilities will make you extremely dangerous.
In fact it'll probably be worth it to get your skills up between now and September when Armored Kill becomes available for download. One word, two syllables: gunship.
