To get the Sting DLC for WWE 2K15 on an RGH Xbox 360, you'll need to download the DLC files from a trusted source that offers modded content. Once downloaded, transfer the files to your Xbox 360's hard drive using a USB drive or through FTP if your console is set up for it. Ensure that the files are placed in the correct directory, typically under the "Content" folder associated with WWE 2K15. Finally, launch the game, and the DLC should be accessible in the game's menu.
