Supremacy: The Unconventional Forces (1989)

The Unconventional Forces expansion focuses on Assassins, Spies, Saboteurs, Biowar, Chemwar, and Envirowar. There are three new decks, Assassins and Spies, Saboteurs, and Special Weapons. There are 15 Assassin cards and 25 Spy cards in one deck. The Assassins are used to kill an officer in a specific territory or sea. The spy can identify a player's amount of money on hand, location of resource cards, type and tech level of any advances, and names and locations of officers. The saboteur does exactly what you'd expect. The Special Weapons cost $500 Million to research and develop. The various Bio/Chem/Enviro warfare techs can be targeted against troops, territories, or resources. Expands: Supremacy: The Game of the Superpowers
