Yes, I have some good news!
Apple has made some changes to the App Store, which means that people with older devices (such as the iPod Touch 2G and iPhone 3G) can now download the last compatible version of Celtic Heroes.
That is, if you do not have Celtic Heroes installed on your device, or you deleted it, you can now download a version of the game and still be able to play. Huzzah!
A word of note: Playing the game on an older device will NOT be the best experience, and because you are downloading an old version of the app some features WILL be missing and there may be some bugs. We can not offer any technical support for players who download an older version of the game. Whilst players on an older version are currently able to connect to the servers, we cannot guarantee that this will be the case forever.
