My friend's birthday next month and I know he likes to play this game. Since I unfortunately do not know something with sowas I wanted to ask if anyone knows if you can buy something for something like a coupon or something or a general coupon so an Xbox coupon or something, but I think so? I've no idea why I'm asking for help
So you can't give him a Rainbow Six coupon. Because something does not exist.
What would happen is the Season Pass. But that only makes sense if you know that he does not have or or which he has. It is currently the 3rd or 4th season. (I would not give that too)
But what would happen is an Xbox Live Gold Coupon. He can then play online against other players.
Optionally also an Xbox Live map (credit card) goes. With this he can buy his wish list across the system.
Always and everywhere: Credit cards can be used on all devices - whether on the smartphone, tablet, PC or Xbox 360
Apps in Windows 8 and Windows Phone 8 Store: With the Xbox prepaid cards, content can be purchased not only in the Xbox Store, but also in the Windows 8 Store (Windows 8.1 and higher) and the Windows Phone 8 Store - including a variety of apps
Xbox Games: Play online with friends, download new games and add-ons, and get exclusive discounts on Arcade Games or Games On Demand titles every week
Xbox Music: Over 30 million songs to discover, stream, download and collect - on TV, smartphone, tablet or PC
Xbox Video: Lend or buy the latest series and movies in HD on the tablet, PC or TV - Xbox Video makes it possible. With Xbox Video content can be enjoyed in HD - no matter where you are
Nevertheless, I would still look for another option in your place. Personally, I do not want from friends, acquaintances or from my girlfriend technology or games. Especially because so many mistakes can always happen.
Sorry
