There are a lot of plus to Valhalla the story isn't bad and the fights early on at least are good till you get the skill to catch thrown weapons and arrows etc. Then just stay ranged against flag bearers and they throw spear. Catch it and throw it back same for archers etc.
The welcome return on a shield was missing in Odyssey come on Roman era and no shield and it is useful without being defense defense hit defense of AC of old.
BUT and it a big BUT!!!! Odyssey go round kill anything and everything this now has the unwelcome return of the aminus ( from the future control of early AC games which made sense).
Raid villages etc well no only kill guards 3 no guards and you reset some fights you kill them as the run past as you fighting a guard. This is supposed to be the blood and ...... of the viking era and we can't do it. Drop the aminus in next AC we don't need it
