Rocksteady be giving us all a free Batman Inc.-style Batman skin for Arkham City, as a "thank ye all for yer incredible support before, during 'n after the game's release," according t' a statement from director Sefton Hill. With that costume, ye'll be all set t' travel the world 'n recruit some international Batmen, although, a course, ye won't actually be doing that. The costume will be offered as a free download tomorrow on Xbox Live, PC, 'n PS3.

The world has opened up for us in other ways, however. Along with this announcement, Hill shared a code that will allow ye t' use any downloadable skin in the campaign without having t' complete it first. At the main menu, after choosing yer save slot, press left, left, down, down, left, left, right, up, up, down. Then all the costumes ye've bought or otherwise acquired will be available. Old school!

If ye really feel like buying stuff, ye have a couple a options there, as well. The "Arkham Bundle" collects the Nightwing Bundle Pack, Robin Bundle Pack, 'n the Arkham City Skins Pack for 1200 MSP ($15); there's also a Challenge Map Pack including the new Batcave map, the Joker's Carnival, 'n the Iceberg Lounge, for 240 MSP ($3). Both be due today.

[Thanks, Nick!]
