A number of Activision's licensed games are no longer for sale on digital storefronts as of this week, including those in the Spider-Man and Teenage Mutant Ninja Turtles series.

Reports recently began to come in that The Amazing Spider-Man and The Amazing Spider-Man 2 had both disappeared from Steam, the PlayStation Store, the Xbox Store, and the eShop. Meanwhile, it's also been discovered that fellow Activision game Teenage Mutant Ninja Turtles: Mutants in Manhattan has also disappeared from the digital platforms it was available on.

Activision has not made any formal announcements regarding the games' removals. GameSpot has followed up with the company and will report back with any response we receive.

While licensed games have disappeared from digital stores numerous times in the past--including some of Activision's--the TMNT one comes as a surprise. The Amazing Spider-Man games were released in 2012 and 2014, respectively, whereas the Platinum Games-developed Mutants in Manhattan debuted less than a year ago, in May 2016. Games are typically delisted due to licensing agreements expiring, but that's an awfully short time for it to have been available.

Previously purchased versions of these games will remain playable, and physical copies remain in circulation. Unless something changes with digital availability, the latter will be your only way of getting your hands on any of these games in the future.
