ArkhamCity.co.uk is reporting on a Best Buy advertisement for Batman: Arkham City spotted by one if its readers, which if correct seems to confirm Robin’s appearance in the game.
According to the ad, if you pre-order from Best Buy you are given access to Robin as “playable character” in two challenge maps.
The ad has since been removed, however you can still see it on Google Cache. There is no word as to whether this is a US only deal or if it will also arrive in Europe as well.
Arkham City is out on October 18 for PC, PS3, and Xbox 360 and you can pre-order a copy by following the links.
