The Moon Cell Automaton is a spiritron computer, which exists on the moon and has the power to grant any wish. All across the spiritron-constructed virtual world, SE.RA.PH, Servants and the Masters who control them fight for the right to be the Moon Cell Automaton's one owner in a ceremonial conflict known as the Holy Grail War.
Now, the Servant Nero Claudius and her Master have won the Holy Grail War and have obtained the universal wishing mechanism, the Holy Grail.
They also obtained the Regalia, a ring that proves their kingship. With it, they rule over their once-enemy Servants and start a new beginning on the moon's new world.
But a new enemy has appeared before them. And this enemy has something that shouldn't exist: another Regalia.
Not just Fate/EXTRA Servants, but characters from Fate/stay night, Fate/Apocrypha, Fate/Grand Order and other Fate continuities make their appearances here. Players can enjoy the action with the original Japanese voice-overs and English subtitles.
As the original creator of Fate/stay night and the scenario writer of Fate/EXTRA, Kinoko Nasu has created a completely new scenario for Fate/EXTELLA, evolving his highly celebrated universe and characters.
The story is told from the independent perspectives of three heroine Servants, augmented by various side stories that help supplement the main storyline.
For the first time, take full control of a Servant and battle through enemy programs using a combination of heavy and light attacks. Take control of the enemy’s sectors to complete the Regime Matrix, forcing the Boss to appear and engaging them in battle to achieve victory. Before starting each stage, a player can select the difficulty level, from Easy to Very Hard (available only after the story has been completely beaten once). Fighting on higher difficulty levels grants better skills and equipment.
Fight across multiple unique sci-fi storylines with ferocity and passion, augmented by powers and features born of the Fate universe's lore.
