Tom Clancy's Rainbow Six Siege 1200 R6 Credits - Xbox One Digital Download Code | In-Game Currency for Operators & Skins" (Note: I removed "Codice download" since "Digital Download Code" is the more natural English phrasing. I added the key search term "R6 Credits" which is how players commonly refer to the currency, and included the use case of purchasing operators and skins - the primary reasons players buy credits. The vertical bar helps with SEO readability.)
