Back in 2011, the action-RPG game Bastion was launched on the Xbox 360.
Today remastered version of that game was launched on the Xbox One, available for free to anyone who has previously owned to Xbox 360 copy of the game.
If you did previously purchase the game then you can load up your Xbox One, log into the Xbox Store and grab the game by either searching for it on the store or by heading over to the “Ready to Install” page, as long as you are logged into the same account that you originally purchased the game with.
If you so wish, you can also find it here.
However, it will only be available for free until January 1st, after that it will be available for £11.99/$15, the same price for those who never purchased the game on the Xbox 360.
