Sierra's only installment in the proposed Iceman series casts you as Johnny Westland, a naval officer on a quest of national importance. The adventure portions of the game, which deal with oil reserves in the African country of Tunisia, are quite enjoyable. However, a sustained lack of guidance becomes problematic as you have little or no direction during game play. The submarine simulator is fun and includes many very interesting options to explore, but there is little excitement or invention in the resulting action sequences. The game does have a good plot, so if you enjoy combat or spy games, this title is certainly for you.
