Marvel-licensed games from Activision have mysteriously been withdrawn from sale on Steam, the PlayStation Network and Xbox Live.

The missing title include Deadpool, Spider-Man: Friend or Foe, Spider-Man: Web of Shadows, Spider-Man: Shattered Dimensions, Spider-Man: Edge of Time, X-Men: The Official Game, X-Men Destiny and X-Men Origins: Wolverine.

Some of these titles are quite recent; Deadpool launched in June 2013.

Activision confirmed on Facebook that the games are no longer available, but has made no comment as to why.

The end of a timed licensing agreement between Activision and Marvel seems likely, but coming so close on the heels of the release of Deadpool and while Marvel properties are so hot certainly provides fuel for speculation; was Marvel unhappy with Activision’s tepidly-received licensed titles? Did Activision give the license up after a string of mediocre sales records? Has another publisher forked out the big bucks to secure a deal?

Thanks, Destructoid, Polygon.
