Robot Commando is a single-player roleplaying gamebook written by Steve Jackson (the American game designer, rather than the series co-creator), illustrated by Gary Mayes and originally published in 1986 by Puffin Books.
It forms part of Steve Jackson and Ian Livingstone's Fighting Fantasy series.
The reader takes the role of a dinosaur rancher in the country of Thalos on a distant planet who finds themself in the middle of an attack by Thalos' mortal enemy, the militaristic Karosseans.
A strange weapon is unleashed which causes all of Thalos, save the protagonist, to fall into a deep sleep and leaves the land free to be invaded.
Robot Commando is one of the few entries in the Fighting Fantasy series to feature multiple successful endings: rampaging through the enemy camp and subsequently drawing out Minos to a robot fight (he'll be on his Supertank); entering the enemy camp straight, speaking out loud the reference number for a one-on-one duel between the rulers of both tribes, drawing out Minos to a sword fight; crafting a blue potion in the City of Knowledge, then adding a leaf of the Man Eater plant, subsequently getting a plane robot and flying straight in to the storm above the City of Adoration.
