Capsule Servant (カプセルさーばんと, ?) is a side-game set to be included with the PlayStation Vita release of Fate/hollow ataraxia. It is to be a “competitive Tower Defense-style game” featuring Masters and Servants from various Fate series titles.
The banter between these two is honestly some of the best in the series. I definitely love how Waver goes from a scaredy cat one second to full on confrontational when it comes to silly things and Rider just sits there arguing back.
