This is official in the store in Bowie, MD.
Walked in around 5pm, went to video game section, saw AC:R with a shelf tag of 39.99. The box had the "Exclusive: Armor of Brutus Unlock" label on it. There were several copies left after I picked up mine. I had no issues.
Devil May Cry 4 was on the list of games yesterday. I had it in my cart but today I deleted it because I wanted to get different games. I look for DMC4 and it's gone...
I am just amazed by the size of Battlefield 3's maps. They are quite expansive...
In fact, from the match I played, I had a bit of trouble finding where enemies were.
