Microsoft celebrates the Xbox One's one year anniversary by giving "early adopters" of the system Limbo for free.

The recently released game from Copenhagen, Denmark-based studio Playdead is a dark 2D puzzle-platformer that was originally released on Xbox 30 in July of 2010. It was later released on PC, PS3, Mac, and PS Vita. The game is also available to everyone else too but if you are not an early adopter you'll have to put some money down to get it.

We assume the eligibility requirements for being called an "early adopter" remain the same as they were when Microsoft announced the Xbox One one year anniversary giveaway plan last week: anyone who bought an Xbox One between November 22, 2013 and November 11, 2014, and has logged at least 10 hours of usage is eligible.
