Assassin's Creed Valhalla will feature some story choices that can impact multiple regions at the same time.

Speaking with VG247, Assistant Level Design Director Laurence Letalien talked about story choices like the one that has been seen in yesterday's gameplay showcase.  These choices will have an impact on the world, but it is not yet clear if they will lead to big story changes.
