Screenshot of the Android version
There’s been comments around that the iOS version of Sonic 4: Episode 2 is no longer found in the iTunes shop.
This is evidenced by finding the page’s url via Google and clicking on it just hangs you on a message saying “Connecting to the iTunes store”. However the Google Cache of the page is still available here.
Good news though, it is still available to Android users in the Google Play shop here. Same goes for Episode 1 on iOS.
We’ll update if any news comes up.
