Starship Troopers: Prepare For Battle! should not be confused with the original Starship Troopers wargame, also by The Avalon Hill Game Co, published in 1976. Starship Troopers was based on the Heinlein book. Starship Troopers: Prepare For Battle! is based on the film version. This is a fast-paced tactical wargame which begins simply and then adds additional rules with each new scenario. Note that the original Starship Troopers game has completely different rules, maps, units, etc.
