Updated: ‘SHADOWGUN’ Gets MFi Controller Support
The update is a little buggy, though – proceed with caution
Classic iOS cover shooter Shadowgun was recently updated for MFi controller support, joining developer Madfinger’s other iOS games Samurai II and Dead Trigger 2 in supporting controllers.

All is not well, though. There are widespread issues with installing this update resulting in lost save files and startup crashes. Personally, I found uninstalling the game and then reinstalling it solved the problem, but your mileage may vary. If you have a copy of this game already installed, and you’re worried about your save file, I recommend holding off on this update for now.
