République Remastered, the graphically-revamped version of the acclaimed stealth action game, has now been released for the Mac. It's also the first commercially-released game to use the new Unity 5 graphics engine.

The game, from developer Camouflaj, was previously released for the iPhone and iPad, using the older Unity 4 game engine. The new Mac version of République Remastered normally costs $24.99, but will be priced at just $19.99 during its launch week. It offers immediate access to the game's first three episodes, and the price also covers the final two episodes when they are released. Here's a breakdown of the game's storyline:

In RÉPUBLIQUE REMASTERED, players assist Hope, a desperate young woman struggling to escape from a secret, Orwellian state. Communicating using a stolen phone, Hope contacts the player and asks them to hack into the nation's surveillance system, assume control, and guide her out of the clutches of the omnipresent Overseer. Literary works such as 1984 and Brave New World, and current geopolitical events including global surveillance and Internet censorship serve as key sources of inspiration for both the narrative and the stealth-survival gameplay. Players expand their control over surveillance cameras and other network-enabled devices, growing into an active threat to the Overseer and his grip over his shadowy nation.

There's also a deluxe version of the game that includes its soundtrack, a "making of" video documentary and what Camouflaj says are "two early prototypes". The deluxe version normally costs $34.99 but during launch week it will cost just $27.99. You can find purchase and download links for both versions at Camouflaj's website.
