Szare Szeregi (Grey Ranks) is a card game about the Warsaw Uprising of 1944. The board depicts 12 regions of Warsaw and players launch multiple attack on the different regions with cards from hand that represent various unit that took part in the conflict. The attacker can field multiple units from hand while the defender can call for support from neighbouring provinces, and the high value wins. When both players' decks run out the winner is the player with more valuable units in the regions he controls.
