In 2014, Square Enix released Hitman GO, a turn-based puzzle game, on iOS and Android. Two years later, the game was re-released as Hitman GO: Definitive Edition on PC, PS4, and Vita.
The Steam page for Hitman GO: Definitive Edition doesn't list any new features or differences when compared to the original, so I'm not sure what makes this new version "definitive".
What's the difference between Hitman GO and Hitman GO: Definitive Edition?
