Like several sci-fi Fighting Fantasies, this book suffers from genre stereotyping and difficulties in converting the high-fantasy FF concept into a different setting. It's a dungeon-crawl style adventure happening entirely onboard an enemy starship, involving a trek to find the enemy "boss" at the end.
What's done well is the conversion of FF combat for the use of laser weapons - the FF rules are modified to create quicker damage, alter the effects of skill and allow armour saving throws. This combat method "feels" very different from the usual FF melee brawls, nicely emphasising the sci-fi setting.
What's done badly is the structure of the adventure. With high initial scores, it's largely too easy - you don't need special items or information at the end, nor to beat a foe with high scores - you just need to find a way through the ship to reach it. The items are mainly red herrings or more rarely, have some minimal non-essential use on one particular random course.
What difficulty there is, comes mainly from sudden-death paragraphs which are frustratingly common and difficult to see coming, especially towards the end. Without any logical or intuitive reason for the effects (to take an example - walking straight at one dangerous opponent gets you a walkthrough, whereas trying to dodge it gets a sudden death paragraph), these can be a major irritant.
The dungeon crawl is far too one-dimensional, involving mainly a series of boring and random choices - left or right button, left right or middle passage, security door or regular door, red green or blue button, through door or down passage - which don't involve any real choice for the player, effectively being matters of luck.
The book also almost completely lacks a plot, the aliens are of B-movie standard (really, in the post Star Wars world we can do better than manic squirrels and cleaners with carrots for ears!), and there's an unexplained and largely inexplicable relapse into a high-fantasy world within the starship on one common course (what's a mass of woods, fields and plains doing on a starship anyway?!).
I'd suggest Robot Commando, Rebel Planet and Star Strider as better examples of sci-fi FF done well.
