To thank you for making their publishers millions of dollars and themselves a swag of awards, Batman: Arkham City developers Rocksteady have unlocked a couple of holiday treats for owners of the game.
First is a "cheat code", which players can enter and which lets them unlock any skins they've earned/accrued without having to actually finish the game.
To unlock this, simply press the following combination on the Main Menu screen (after you have selected your save slot):
- Left, Left, Down, Down, Left, Left, Right, Up, Up, Down.
And if you don't have a code? That's the second treat, with everyone able to later today download a free Batman skin, based on Grant Morrison's Batman Incorporated storyline.
