By Fire and Sword is a realistic, playable and dynamic wargame which recreates the 17th century wars fought by the Polish-Lithuanian Commonwealth against Turkey, Muscovy, Sweden, Crimean Khanate and Cossacks. The period between 1640 and 1676, on which the game focuses, is a time of almost constant warfare waged by the Polish-Lithuanian Commonwealth on all fronts, in many cases with several enemies at the same time. Supplements planned for the game will be dedicated to specific wars and campaigns in which the Polish-Lithuanian Commonwealth took part during the entire 17th century.
