Unfortunately, this is exclusive to our readers in the UK, but the 1970's Batman costume pictured to the left has just been revealed to be a pre-order bonus at retailer Shopto.net for Arkham City. This has become the third major bonus announced in retail versions, with Robin coming as bonus for Best Buy pre-orders and Joker's Funhouse Challenge Room coming with the Gamestop pre-order.

As of now, there is no plans to release the above pictured costume for the US market, but of course these types of things are always subject to change. Check back for more news on this matter.
