The Battle of Castle Itter was fought near the Austrian village of Itter on May 5, 1945, in the last days of the War in Europe during World War II. US soldiers joined forces with Wehrmacht infantrymen, an SS officer, an Austrian resistance fighter, and recently freed French prisoners of war to defend the castle against an attacking force from the 17th SS Panzergrenadier Division.
During a game of Castle Itter, you take the role of the force that defended the castle from on May 5, 1945. The goal of the game is to last until the SS deck is depleted, without allowing SS Counters to reach the castle. You score points for each Defender that survives the assault and lose points for each SS Counter remaining on the board at the end of the game - the higher your score, the better.
