Crossplay

Is Fate/Hollow Ataraxia crossplay?

Fate/Hollow Ataraxia is only released on one platform, so there is nothing to cross-play with.

Fate/Hollow Ataraxia is a Japanese visual novel game and the sequel to Fate/Stay Night. The word ataraxia in the title is a Greek term for tranquility, giving the title the combined meaning of "empty (or false) tranquility". The plot of Fate/Hollow Ataraxia is based half a year after the events of Fate/Stay Night. Like its preceding counterpart, the story is set in Fuyuki City. Bazett Fraga McRemitz, a member of the Mages' Association and a master in the Fifth Holy Grail War, wakes on the fourth day of the Fifth Holy Grail War with a new servant, Avenger, and no memory of what happened to her beforehand. She and the Avenger set off to fight and win the Holy Grail War.
