These are some awesome skins for the game if you are a big fan of Batman. You can use the skins throughout the game all the game modes. You just have to pick which skin you would like to use before you enter the main campaign or one of the challenges. These skins don't really change the gameplay but change how you look at the gameplay which is really nice since this game takes awhile to beat. This downloadable content only affects Batman. When you buy it you will have to input the cd key that comes with this downloadable content into your Games for Windows account and then it will be available on the Steam version. Im really glad i got this and have really enjoyed it. If you like changing the look of Batman and really like new looks then this is a must have for Batman fans.
