Several Xbox One users who bought the console near launch are reporting that they've received thank you notes from Microsoft saying that they'll get a free copy of the indie platformer Limbo when it's released.

Developer Playdead's game, which was first released on the Xbox 360, has yet to be officially announced for the Xbox One, but it was listed for the console on a Korea-based ratings board last month.

Today is the official one year anniversary of Xbox One, and a post to Major Nelson's blog explains that Microsoft is celebrating the occasion by giving away a range of digital content "to show our appreciation for your loyal and continued support." Strangely, Limbo isn't one of the games Microsoft said you might get for free.

Only Xbox One owners who bought their console before November 11, 2014 in the console's 13 launch markets who are 17 years or old and have played 10+ hours on Xbox One are eligible. You can find the full list of possible free gifts here.
