If you want to buy Destiny on the day of release but you are in two minds because of that plan to invest in the next generation console. Well, have no fear. Activision are offering users a deal which allows you to buy the digital download for your Xbox 360 or PS3 and this will instantly grant you access to a free copy on the next gen Console.
The deal runs until January 15th of 2015, and the console you have now will dictate the the version you can buy for your next system. For example, if you have an Xbox 360 you will only have access to the Xbox One version, and the same goes for PlayStation users.
The process for being able to download your free digital copy is explained here.
