A public domain adaptation of Havoc: the Hundred Years War using a regular deck of cards.Aside from differences in number (players are dealt 5 cards, only 2 cards are placed as 'recruits', etc.) and cosmetic differences (2s are used in place of 'Dogs', Jokers as pairs of Dogs, etc.) the significant differences is the use of the face up recruit cards and a randomly drawn card to determine the point value of each battle at the moment it is called. This changes the game considerably as it eliminates the role of strategy about future battles, which is an important element of Havoc. - BoardGameGeek
