Cook Wars is a cooking themed party game similar to the Cooking Mama series. The player can choose between four characters from four countries (Japan, USA, France and Italy) each with different specialties. Then you have to select a recipe to begin, here again the meals are sorted by country of origin, for example France will have Ratatouille, Crepes, Cheese Fondue and Croissants. More recipes can be unlocked as the player progress.
Mini-games have the player use the Wiimote to chop vegetables, flip crepes in a pan or crush tomatoes to make sauce etc. Score points are awarded for speed and accuracy of the players movements. Up to four players can compete with each other in multiplayer mode.
