Getting Started in The Witcher 4

Ciri's fighting style leans into agility and speed rather than Geralt's more grounded, block-based approach — expect a more mobile playstyle from the outset.
Mobile spellcasting is a confirmed new mechanic — Ciri can cast Signs while walking, something Geralt couldn't do in the original trilogy.
Geralt will still appear in the game, though in a reduced role, so returning fans will see a familiar face even with Ciri at the center.
The game canonizes The Witcher 3's ending in some form, so prior knowledge of Ciri's arc there may carry narrative weight.
