After becoming a freemium game for Android, FPS from Madfinger GAMES (from 'Shadowgun') is now also freemium on Apple devices.

In the Android version, what led the game to become free was the high rate of piracy, which made the producer worried and decided to turn the game into Freemium, since in addition to the player paying US$ 0,99 for the game, he should also shell out a few dollars for in-app in-game items.
As for the iOS version, it was not clear why the game became Freemium, even why iOS is not piracy-free (don't confuse Jailbreak with piracy), but apparently it made no sense for 'Dead Trigger' to be a paid game from the start, as the main focus of the money raised is on in-app purchases that can exceed $10.
In summary, just like on Android, 'Dead Trigger' is now free also on iOS, the game requires a 3rd generation device or higher, iOS 4.2 or higher and 140 MB (pada Download), you can download it by clicking here (AppStore)
