Common gameplay
The game plays as an action focused 3D beat 'em up, having you be able to play as either Regina or Selina (although Selina later on in the first game) as they have a primary weapon which is a sword that can morph into a gun. Both Regina and Selina are both allowed to have one secondary weapon which can either be melee or ranged. They also are able to use runes which are a source of magic. Both Regina and Selina are only allowed to have five runes on their suit at a time as several runes have different uses. The game also has bits of exploration as well as having a mission based structure with side missions being able to be played too.
