Cthulhu: Tora! Tora! Tora! is a two player, print and play boardgame that sets Kamikaze fighter pilots against the Great Old One Cthulhu.
This game was designed as the final work for a Game Design course. It started as a modding of Sink the Bismark (http://www.boardgamegeek.com/game/38702), but acquired a new theme and new game mechanics based on "Purrinha".
