Extraterrestrial Grail is a free, off-line, single-player, turn-based strategy/board game in which you play against 1-3 computer players. Extraterrestrial Grail takes place in outer space in which you are an alien searching for the Grail. Only one player gets the Grail at the beginning of the game, so the other aliens must find out where it is by fighting each other and searching planets for it. The object of the game is to have the Grail card in your hand when time runs out.
