It was published by Bully Pulpit Games, in the US and designed by Jason Morningstar.

It proved a huge success in America, though has not found its way to Poland yet. ‘Grey Ranks is a game for three to five players’, write the publishers, ‘that puts you in the shoes of child soldiers during the Warsaw Uprising. The game is designed to be played over three sessions and includes a scene structure, with each scene corresponding to a specific date in 1944.

As the game progresses, success becomes increasingly difficult and the player is  faced with difficult choices. The characters have all the faults and enthusiasms of youth. Across sixty days of armed rebellion, they will grow up fast - or die’.

The designer, Jason Mornigstar said he wanted to create a dramatic game and at the same time show the many sacrifices and hardships of the Warsaw insurgents.
