With this update we’ve migrated IT’S TANKS! to Unity 4 which allows us to use dynamic fonts for player names.  This means full unicode character support for all characters in Game Center aliases, if we have missed something please let us know: feedback [at] bitbybitgames.co.uk

The change to Unity 4 should also see a small performance increase on lower end devices.

This update can be downloaded now from the App Store:
