Fate/EXTRA is an alternate look at the Fate series' Holy Grail War. The game features characters from other installments such as Fate/Stay Night, Fate/Zero, and other Type-Moon works.
 Game Play
Fate/EXTRA lets you pick between a boy and a girl protagonist, and one of three Servants; Saber, Archer or Caster. Gameplay works in an exploration of large dungeon areas, and combat uses a Rock-Paper-Scissors formula with an additional skill system. Battles work with enemies having certain patterns of attack, and the more you fight them, the more moves you can see they'll use, letting you have a better idea of what pattern is coming up.
Depending on your Protagonist Gender and Servant, it is possible to have romantic relationships with your Servant and characters in the game.
Fate/EXTRA has a fully voiced cast from the original Fate/Stay Night, and new actors for the new cast. The game features different possible perspectives depending on the player gender and Servant, so the game offers a wide range of replayabilty.
