Microsoft Studios
"Charlie Murder" was the third Ska Studios game published by Microsoft Studios. During development, Microsoft Studios provided Ska Studios with usability testing and play testing feedback, handled localization, and found and suggested bug fixes. Microsoft required Ska Studios to create picture packs (Xbox Live account customizations), but was not responsible for the Windows Phone 8 game mechanic. Ska Studios had complete creative control over the game itself. "Charlie Murder" was promoted as a free Xbox download with Microsoft's Games with Gold program during the month of June 2014.
