Shogo: Mobile Armor Division is a first-person shooter video game developed by Monolith Productions and published by Monolith and Interplay Entertainment in 1998. The game features on-foot first-person shooter action, and combat with anime-style bipedal mechs. Shogo is a combat system that features the possibility of critical hits, whereby attacking an enemy will occasionally bring about a health bonus for the player. Players take on the role of Sanjuro Makabe, a Mobile Combat Armor (MCA) pilot and a commander in the United Corporate Authority (UCA) army, during a brutal war for the planet Cronus and its precious liquid reactant, kato. Players must locate and assassinate a rebel leader known only as Gabriel. At two pivotal points in the game, the player also has the opportunity to make a crucial decision, which can alter the game's ending. Shogo was initially known as Riot: Mobile Armor, and it is heavily influenced by Japanese animation, particularly Patlabor and Appleseed, and the real robot mecha genre. The game was received positively by critics, and it shipped 100,000 units of the game to retailers in the game's debut week. It underperformed commercially, selling roughly 20,000 units in the United States during 1998's Christmas shopping season. Despite this, Shogo's critical success led to Monolith's development of a later game, The Operative: No One Lives Forever. Shogo was ported to the Amiga PowerPC platform in 2001 by Hyperion Entertainment. Hyperion also made the Macintosh port and the Linux port of Shogo.
