Limbo was given out for free to certain Xbox One owners and Microsoft has now confirmed the criteria for this gift.
Apparently anyone who used their Xbox One during the console's launch weekend should now have a code for Limbo in their inbox, while the platformer's new Xbox One port will be made available to purchase for everyone else "soon".
"We're looking forward to launching Limbo on Xbox One," a Microsoft spokesperson said. "As a thank you to our earliest adopters, fans who played their Xbox One the first weekend of launch received early, free access to the game.
"Limbo will also be available for purchase via the Xbox Game Store soon."
It's being rumoured that Limbo could be one of the Games with Gold for December, so don't feel too put out if you don't have a copy yet.
