Cool series to see a climbing system similar to Zelda Breath of the Wild, this would make the game movement more fluid, especially in mountainous regions, imagine just climbing a mountain to face a boss, it would be very cool.

It would be really cool to have to do some climbing and parkour to get somewhere or do some mission or maybe even access some secret places that would only be accessible through climbing and parkour.
