You are Sanjuro Makabe. Your friends and family are dead and everyone blames you. It really wasn't your fault yet the freak accident has cost you so much pain. You're literally frowned upon by your peers and your career has taken a nosedive into a shallow pool. Just when you thought things couldn't get worse, a terrorist organization is now threatening the Cronian Mining Consortium (the government) and your military commune. Their leader, Gabriel, is planning to overthrow the government and it is now up to you to stop him. There are also rumors that the terrorists are actually responsible for the loss of your loved ones and thus you head out on a path of redemption, revenge and the destruction of the Fallen and Gabriel himself.
This is the premise for Shogo: Mobile Armor Division, a mecha-action game from the makers of Blood. In it, you chose one of four different MCA (Mobile Combat Armor) units and romp through the planet of Cronus (in first or third person perspectives) looking for Gabriel and stopping his terrorist organization from any wrongdoing. You'll battle it out in military bases and starships as well as vast outdoor atmospheres such as deserts and valleys. Fortunately, your military company has been researching new technology to produce weapons of mass destruction -- 18 in all. At your disposal is the destructive Juggernaut, pulse cannons, rockets, etc.
