An update based on previous post, this is a new gameplay vid on the first boss fight.
The boss name is Wrath; a fair bit of warning for spoilers if you do not want to see the first boss design.
As you can see from the video, unlike Kratos(God of War); Fury’s moveset seems to be reliant on one hand motion swing (right hand) instead. You get to feel the motion of dodging back, side and a counter with a downward slam using the chain weapon, hence timing is vital for this boss fight.
And no, there is no QTE or ending epic killing cinematic blows.
Not much is there to be WOW about. But a slightly more in depth piece on how she fights her first boss.
