Now we have only confirmation that US pre-order bonuses are available at this time for Batman: Arkham City, but I’m sure that will change. I’m also pretty sure we will be seeing more pre-order bonuses at of right now it is just Best Buy and Gamestop. Gamestop will get you an additional Challenge Map called ‘Joker’s Carnival’. Best Buy will get you a ‘Combo Pack’ bundled with it and as far as what is in it at this point.. no idea. Soon the contents of it will be revealed as well as more pre-order bonuses and more details, pics of the bonuses. Batman: Arkham City will be Co-Published by Warner Bros. Interactive and Eidos Interactive as it will be Developed once again by Rocksteady Studios. The game will be released on October 18, 2011 for the Xbox 360, Playstation 3 and PC.
Keep periodically checking the official pre-order page for updates. The page gives links to pre-order the game at Walmart, Gamestop, Amazon.com and Best Buy leading me to believe all retailers will eventually have pre-order bonuses, but I could be wrong. Keep it here for the latest.
