This week's issue of Famitsu has the scoop on a new game in the Fate series. Fate/Extella is in the works for PlayStation 4 and PS Vita, and it's gearing up to bring a more action-oriented spin on the Fate series to Japan sometime this year.
The issue confirms three Servants so far: Saber Nero Claudius, Caster Tamamo-no-Mae, and Saber Alter. Kinoko Nasu and Hikaru Sakurai are handling the scenario, with Arco Wada on character designs for the game, which is set after the Holy Grail War of the Moon. Extella is the name of the moon's new world, and Fate/Extella is aiming to be much more than a simple Fate/Extra sequel.
You can see some of the action-based approach if you squint at the screens:
