Right about now, Battlefield 3 Premium users are feeling good about their decision to purchase the super upgrade package because the Armored Kill add-on pack is making its way to the Playstation 3 as you read this. Non Premium PS3 folks can get AK as well, but you'll have to drop a payment to do it and it's not available to you until the 18th. Xbox 360 Premium gamers have to wait until next week for Armored Kill.
For those of you who still haven't thrown down the $50 for BF3 Premium --which gets you all of the add-on content early-- good luck finding and being able to buy just the Armored Kill pack. It'll set you back $14.99 or the equivalent thereof, but EA really really wants folks to throw in for the whole $50 as the calendar of add-on content gets close to the end. Remember though, getting Premium now will get you the new stuff that's still to come in addition to the add-on packs that have already come out and are now old.
Watch this Armored Kill trailer and see if you're motivated to dig into your pocket.
