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. It is the first game to use the LithTech game engine. 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.

Shogo features a mix of both standard on-foot first person shooter action, and combat with anime-style bipedal mechs. Unlike mech simulator games such as the MechWarrior series, the mechs in Shogo are controlled essentially the same as in first-person shooter games.^{[citation needed]}

An inherent feature of the combat system in Shogo is the possibility of critical hits, whereby attacking an enemy will occasionally bring about a health bonus for the player while the enemy in question loses more health than usual from the weapon used. However, enemy characters are also capable of scoring critical hits on the player.

The game revolves around the struggle to secure reserves of "kato", an energy source that makes interstellar travel possible. Players take 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.Originally intended as a joint venture that would ensure the continued profitability of the three organizations that founded it, the UCA is now independent, and the dominant military power in existence. Most of the game takes place on Planet Cronus or the spaceship Leviathan.

Players must locate and assassinate a rebel leader known as Gabriel, who leads the terrorist group known as The Fallen. Prior to the game's first level, Sanjuro had lost his brother, Toshiro; his best friend, Baku; and his girlfriend, Kura, during the war. He is now driven by revenge and his romantic relationship with Kathryn, Kura's sister; in Sanjuro's words, "It's kinda complicated."

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. While the first decision is almost purely a narrative decision, the second decision actually determines who the player will be facing the rest of the game and how the game will end.

Shogo was originally known as Riot: Mobile Armor. It has heavy influences from Japanese animation, particularly Patlabor and Appleseed and the real robot mecha genre. The game runs on a proprietary engine known as LithTech.
