How to play Spriggan: Lunar Verse on Mac

Many years ago, an ancient civilization known for their advanced technology once ruled Earth, but were destroyed in the end by their misuse. So, they left messages for later generations in the form of indestructible message plates written in ancient Hebrew, informing them that if they could not find a good use for their creations, they should be destroyed. Various paramilitaries, national armies, and armed private forces began to secretly search for these "mysterious artifacts" in order to be used for their own good and against their enemies. The ARCAM Corporation and their military arm, the ARCAM Private Army, can stop these forces from destroying themselves with their elite secret agents known as Spriggans.
