Activision's James Bond games have been removed from a variety of digital platforms.

Steam users noticed that Quantum of Solace, Blood Stone and 007 Legends had each mysteriously disappeared from the online store earlier this week, amidst speculation that the publisher's right to use the James Bond license had expired.

The games have also been removed from Activision's own digital store, while Games on Demand versions of Blood Stone, Quantum of Solace, and GoldenEye 007 Reloaded have each been taken down from Xbox LIVE Marketplace.

However, it isn't yet known for certain why the games have been removed, whether they'll reappear, or why the decision to pull them only seems to affect certain platforms.

A digital version of 007 Legends is still available to purchase on PlayStation Store, for example.

According to a GameSpot report published at the time of the license's acquisition, Activision's right to use the James Bond license expires in 2014. has contacted Activision for comment.
